ng-bind-html not working

I'm trying to insert HTML into my div (bottom of code). I've dealt with an issue like this before so I added a filter. However, when the div is made visible through a toggle function the HTML doesn't display from the service. I have verified that the service is returning the proper HTML code.
The div is unhidden but no html is displayed.
Angular Code:
var myApp = angular.module('myApp', []);
angular.module('myApp').filter('unsafe', function ($sce) {
return function (val) {
if ((typeof val == 'string' || val instanceof String)) {
return $sce.trustAsHtml(val);
}
};
});
myApp.controller('myAppController', function ($scope, $http) {
...
SERVICE CODE
...
$scope.toggleHTMLResults();
$scope.HTMLjson = obj[0].HTML;
HTML Code:
<div id="returnedHTML" ng-bind-html="HTMLjson | unsafe " ng-hide="HTMLResults">NOT HIDDEN</div>
I'm not sure why this isn't working.
Here is my Plunker

There were multiple things wrong with your example.
Main Javascript file declared twice, first in header and second before close on body tag
You call a function as HTMLAPI() instead of $scope.HTMLAPI()
Your $scope.HTMLAPI() function was also being called before it was initialised
Fixed controller code:
app.controller('myAppCTRL', ['$scope', '$http', function ($scope, $http) {
var API = this;
$scope.HTMLInput = true;
$scope.HTMLResults = true;
$scope.toggleHTMLInput = function () {
$scope.HTMLInput = $scope.HTMLInput === false ? true : false;
}
$scope.toggleHTMLResults = function () {
$scope.HTMLResults = $scope.HTMLResults === false ? true : false;
}
$scope.HTMLAPI = function (HTML) {
var newJSON = ["[{\"ConditionId\":1111,\"ConditionDescription\":\"<i>DATA GOES HERE</i>\",\"ErrorId\":0,\"DisplayId\":0,\"DisplayName\":\"\",\"ErrorValue\":\"\"}]"];
var obj = JSON.parse(newJSON);
$scope.HTMLjson = obj[0].ConditionDescription;
$scope.toggleHTMLResults();
console.log($scope.HTMLjson);
}
$scope.HTMLAPI();
}]);

How to ensure that a scope variable updates and binds before going to view angularjs

In my code, there is this scope variable called $scope.detailsPresent which basically just checks if there is data and displays a different page based on the result.
What happens is that when i do console.log($scope.detailsPresent) the value is correct based on if there is data which the value should be false or if there is no data the value should be true.
But the view doesnt bind the value yet so on the view the value is not yet updated hence it doesnt show the correct page. How do i ensure that the value is updated in the view ? I have tries $scope.$apply() but i get an error so is there anyway to do it?
my_controller.js
angular.module('my.controllers')
.controller('ReferralCtrl', function($scope, $rootScope, $window, $state, $q, $timeout, referralCasesGroupByCaseStatus, AuthenticationService, $ionicLoading) {
$scope.detailsPresent = {myVar: false};
$scope.showCaseStatusFromDashboard = function(number) {
$timeout(function() {
$scope.$applyAsync(function() {
$rootScope.fromDashboard = true;
})
}, 1000, true);
$scope.showCaseStatus(number);
}
$scope.showCaseStatus = function(number) {
if(changedNumber !== 0 && changedNumber !== number) {
changedNumber = number;
}
else {
if(changedNumber > 0) {
$scope.$applyAsync($scope.detailsPresent.myVar = true);
}
}
$timeout(function() {
$scope.$applyAsync(function() {
referralCasesGroupByCaseStatus.showCaseStatus(number, $rootScope.listingDetails).then(function(listingCaseStatus) {
$rootScope.listingByCaseStatus = angular.copy(listingCaseStatus);
if(listingCaseStatus == 0 || listingCaseStatus == undefined || listingCaseStatus == null) {
$scope.detailsPresent.myVar = true;
$scope.changeNumber = true;
$state.go('app.case_status')
}
else {
$scope.detailsPresent.myVar = false;
$scope.noMoreItemsAvailable = false;
$scope.changeNumber = true;
$state.go('app.case_status')
}
})
})
}, 1000);
}
my.html
<ion-view view-title="Case Status">
<ion-content>
<div ng-if="detailsPresent.myVar">
<ng-include src="template='no-listings'"></ng-include>
</div>
<div ng-if="!detailsPresent.myVar">
<ng-include src="'templates/case-listings.html'"></ng-include>
</div>
</ion-content>
</ion-view>
I have been on this for about 6days but no success in sight. Any help is deeply appreciated.

This isn't a full answer, but I have some suggestions. This would work better as a comment, but I don't have enough reputation yet.
Try switching your ng-if attributes to ng-show attributes. I realize this leaves the included elements in the DOM, but it might work for you if the performance is not seriously affected.
Also, the reason you get an error when calling $scope.$apply() is because you're already within a call to $apply(), or rather $applyAsync().
See this answer for more details on $apply()

Angular auto trigger specific directive in ng-repeat

I have an interesting situation.
I have a directive with isolate scope that generate list of numbers and the user can choose numbers like in lottery.
The problem i have is that i required minimum of 1 line, if the user pick only one line so when he click play i want to auto trigger the next directive in the ng-repeat to pick for him numbers, I made this plunker so you guys can understand better and help me.
http://plnkr.co/edit/vWGmSEpinf7wxRUnqyWq?p=preview
<div ng-repeat="line in [0,1,2,3]">
<div line line-config="lineConfig">
</div>
</div>
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.lineConfig = {
guessRange: 10
}
$scope.lines = [];
$scope.$on('lineAdded', function(event, line) {
$scope.lines.push(line);
});
$scope.play = function() {
/// here i want to check if $scope.lines.length
//is less then one if yes then auto trigger the next
//line directive to auto do quick pick and continue
}
})
.directive('line', function() {
return {
restrict: 'A',
templateUrl: 'line.html',
scope: {
lineConfig: '='
},
link: function($scope, elem, attr) {
var guessRange = $scope.lineConfig.guessRange;
$scope.cells = [];
$scope.line = {
nums: []
};
$scope.$watch('line', function(lotLine) {
var finaLine = {
line: $scope.line
}
if ($scope.line.nums.length > 4) {
$scope.$emit('lineAdded', finaLine);
}
}, true);
_(_.range(1, guessRange + 1)).forEach(function(num) {
$scope.cells.push({
num: num,
isSelected: false
});
});
$scope.userPickNum = function(cell) {
if (cell.isSelected) {
cell.isSelected = false;
_.pull($scope.lotLine.nums, cell.num);
} else {
cell.isSelected = true;
$scope.lotLine.nums.push(cell.num);
}
};
$scope.quickPick = function() {
$scope.clearLot();
$scope.line.nums = _.sample(_.range(1, guessRange + 1), 5);
_($scope.line.nums).forEach(function(num) {
num = _.find($scope.cells, {
num: num
});
num.isSelected = true;
});
}
$scope.clearLot = function() {
_($scope.cells).forEach(function(num) {
num.isSelected = false;
});
$scope.line.nums = [];
}
}
}
})

You could pass the $index (exists automatically in the ng-repeat scope) - variable into the directive and cause it to broadcast an event unique for ($index + 1) which is the $index for the next instance.
The event could be broadcasted from the $rootScope or a closer scope that's above the repeat.
Then you could capture the event in there.
Probably not the best way to do it.
I can try to elaborate if anything is unclear.
EDIT
So I played around alittle and came up with this:
http://plnkr.co/edit/ChRCyF7yQcN580umVfX1?p=preview
Rather
Rather than using events or services I went with using a directive controller to act as the parent over all the line directives inside it:
.directive('lineHandler', function () {
return {
controller: function () {
this.lines = [];
}
}
})
Then requiring 'lineHandler' controller inside the 'line' directive - the controller being a singleton (same instance injected into all the line directives) - you can then setup that controller to handle communication between your directives.
I commented most of my code in the updated plnkr and setup an example of what I think you requested when clicking in one list - affecting the one beneath.
I hope this helps and if anything is unclear I will try to elaborate.

Angular Inter-Directive Communication

I have created the following simple code with several directives (I have experience with Angular only for several months).
I have used unusual way to make some basic inheritance (as You can see from the Directive class), parameters by default (using ||), possibility to insert one element into another (using transclude), have added directory-specific controllers and of course, specified the link function to support DOM events handlers.
Currently I am trying to call function specified in another directory controller through it's scope, but it fails. The error is 'Uncaught TypeError: undefined is not a function'.
My target is to call controller's function independently from the DOM structure (the target element could be sibling, parent or child). I have considered also shared service and broadcast events, but it seems not the right way to make the communication.
Why the code doesn't work properly?
Are there any other ways to make it?
Thanks in advance.

AngularJS : How to run JavaScript from inside Directive after directive is compiled and linked

I have a responsive template that I am trying to use with my Angularjs app. This is also my first Angular app so I know I have many mistakes and re-factoring in my future.
I have read enough about angular that I know DOM manipulations are suppose to go inside a directive.
I have a javascript object responsible for template re-sizes the side menu and basically the outer shell of the template. I moved all of this code into a directive and named it responsive-theme.
First I added all the methods that are being used and then I defined the App object at the bottom. I removed the function bodies to shorten the code.
Basically the object at the bottom is a helper object to use with all the methods.
var directive = angular.module('bac.directive-manager');

Originally the App.init() object method would be called at the bottom of any regular html page, and I have others that do certain things also that would be used on specific pages like Login.init() for the login page and so forth.
I did read that stackoverflow post
"Thinking in AngularJS" if I have a jQuery background? and realize that I am trying to go backwards in a sense, but I want to use this template that I have so I need to retro fit this solution.
I am trying to use this directive on my body tag.
<body ui-view="dashboard-shell" responsive-theme>
<div class="page-container">
<div class="page-sidebar nav-collapse collapse" ng-controller="SidemenuController">
<sidemenu></sidemenu>
</div>
<div class="page-content" ui-view="dashboard">
</div>
</div>
</body>
So here is my problem. This kinda sorta works. I don't get any console errors but when I try to use my side menu which the javascript for it is in the directive it doesn't work until I go inside the console and type App.init(). After that all of the template javascript works. I want to know how to do responsive theme stuff in these directives. I have tried using it both in the compile and link sections. I have tried putting the code in compile and link and calling the $scope.App.init() from a controller and also at the bottom after defining everything. I also tried putting this in jsfiddle but can't show a true example without having the console to call App.init().
My end design would be having some way to switch the pages through ui-router and when a route gets switched it calls the appropriate methods or re-runs the directive or something. The only method that will run on every page is the App.init() method and everything else is really page specific. And technically since this is a single page app the App.init() only needs to run once for the application. I have it tied to a parent template inside ui-router and the pages that will switch all use this shell template. There are some objects that need to access other to call their methods.
Im sorry in advance for maybe a confusing post. I am struggling right now trying to put together some of the ways that you do things from an angular perspective. I will continue to edit the post as I get responses to give further examples.

You said I have read enough about angular that I know DOM manipulations are suppose to go inside a directive but it sounds like you missed the point of a directive. A directive should handle DOM manipulation, yes, but not one directive for the entire page. Each element (or segment) of the page should have its own directive (assuming DOM manip needs to be done on that element) and then the $controller should handle the interactions between those elements and your data (or model).
You've created one gigantic directive and are trying to have it do way too much. Thankfully, you've kinda sorta designed your code in such a way that it shouldn't be too hard to break it up into several directives. Basically, each of your handle functions should be its own directive.
So you'd have something like:
.directive('sidebarMenu', function(){
return {
template: 'path/to/sidebar/partial.html',
link: function(scope, elem, attrs){
// insert the code for your 'handleSidebarMenu()' function here
}
};
})
.directive('horizontalMenu', function(){
return {
template: 'path/to/horizontal/partial.html',
link: function(scope, elem, attrs){
// insert the code for your 'handleHorizontalMenu()' function here
}
};
})
and then your view would look something like:
<body ui-view="dashboard-shell" responsive-theme>
<div class="page-container">
<div class="page-sidebar nav-collapse collapse">
<horizontal-menu></horizontal-menu>
<sidebar-menu></sidebar-menu>
</div>
<div class="page-content" ui-view="dashboard">
</div>
</div>
</body>
And then you don't need a SidebarmenuController because your controller functions shouldn't be handling DOM elements like the sidebar. The controller should just handling the data that you're going to display in your view, and then the view (or .html file) will handle the displaying and manipulation of that data by its use of the directives you've written.
Does that make sense? Just try breaking that huge directive up into many smaller directives that handle specific elements or specific tasks in the DOM.
