How do I get $emit to controller from directive built html

I'm having difficulty figuring this out. I have a directive building html from promise data. For each row, it's adding buttons for CRUD operations. I do not know how to get the button event to trigger in my controller. Regardless of how my controller is set up, how can I get the event to register in my controller? I am currently trying $emit, but nothing seems to happen.
Directive generated html:
controls = controls+'<button type="button" data-tooltip-placement="bottom" data-tooltip="'+action.name+'" ng-click="$emit(&apos;'+action.broadcaster+'&apos;,'+rowId+')" name="'+action.name+'" class="btn btn-xs btn-default ng-scope"><i class="'+action.icon+'"></i> </button>'
How it looks in Chrome tools:
<button type="button" data-tooltip-placement="bottom" data-tooltip="delete" ng-click="$emit('removeOrgCourse',134)" name="delete" class="btn btn-xs btn-default ng-scope"><i class="fa fa-trash-o"></i> </button>
and my controller listener:
$scope.$on('removeOrgCourse', function( event, data ){
console.log(data);
});
UPDATE:
Just changed the ng-click to console.log("click") and nothing happened. So the issue is that ng-click is not registering;

While you can use events in angular to achive that, one other option is to use & expression scope binding to pass controller method to directive. Example code (from egghead.io)(see working code at jsbin):
<div ng-app="phoneApp">
<!-- we've replaced the use of $scope with the preferred "controller as" syntax. see:http://toddmotto.com/digging-into-angulars-controller-as-syntax/ -->
<div ng-controller="AppCtrl as appctrl">
<div phone dial="appctrl.callHome(message)"></div>
<div phone dial="appctrl.callHome(message)"></div>
<div phone dial="appctrl.callHome(message)"></div>
</div>
Controller:
app.controller("AppCtrl", function() {
var appctrl = this;
appctrl.callHome = function(message) {
alert(message);
};
});
And directive:
app.directive("phone", function() {
return {
scope: {
dial: "&"
},
template: '<input type="text" ng-model="value">' +
'<div class="button" ng-click="dial({message:value})">Call home!</div>'
};
});

Maybe you have to use $broadcast, depends if the controllers are on the same level or who's over who.
Working with $scope.$emit and $scope.$on

in the secon link you can put the $emit and $broadcast in the same controller and see whad do you catch in you $on

ng-click does not work

I'm programming a single-page web application, mostly using the AngularJS framework, and am encountering a problem while using the ng-click directive.
This directive actually does nothing upon click. The linked method is not called (I can't debug it).
Below the code in question:
template file:
<div ng-controller="BonusCtrl as bonusManager">
<!-- [...] -->
<button style="margin-top: 5px"
class="btn btn-success" ng-click="add()"><i class="fa fa-plus"/> Règle de calcul</button>
<!-- [...] -->
</div>
controller:
idServerApp.controller('BonusCtrl', ['$scope', 'webService', 'math', 'DATERANGE_OPTIONS', function ($scope, webService, math, DATERANGE_OPTIONS) {
$scope.add = function() {
console.log('foo'); // no call
var newItem = {
brandId: undefined,
days: 0,
priceMinEVAT: 0,
bonus: 0
};
$scope.rules.push(newItem);
};
Do you have any idea of the problem?
Edit 1
I tried to replace bonusManager.add() by add() and BonusCtrl.add().
I then tried to replace $scope by this, or to remove the controllerAs.
Complete JSFiddle (using some of my services)
Edit 2
Thanks for your answers. I found the solution myself, and it was crappy.
I forgot a closing div tag in the HTML template, so the controller was not defined.

I get your code and made an running example with two cases.
First one using BonusCtrl
$scope.add = function () {...}
ng-click="add()"
And second with bonusManager
this.add = function () {...}
ng-click="bonusManager.add()"
For me it should works just fine. Please let me know if you have any other issues.
var app = angular.module('myapp',[]);
app.controller('BonusCtrl', ['$scope', function ($scope) {
$scope.add = function() {
console.log('Hey you\'ve just invoked add() function!'); // no call
var newItem = {
brandId: undefined,
days: 0,
priceMinEVAT: 0,
bonus: 0
};
};
this.add = function () {
console.log('You can invoke function using \' bonusManager.add()'); // no call
};
}
]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
<h1>NG-CLICK EXAMPLE</h1>
<div ng-controller="BonusCtrl as bonusManager">
<button style="margin-top: 5px"
class="btn btn-success" ng-click="add()"><i class="fa fa-plus"/>add()</button>
<button style="margin-top: 5px"
class="btn btn-success" ng-click="bonusManager.add()"><i class="fa fa-plus"/> bounsManager.add()</button>
</div>
</div>
However you can always use your

Check the working demo: JSFidde
You are using <div ng-controller="BonusCtrl as bonusManager">, so call it like:
<button style="margin-top: 5px" class="btn btn-success"
ng-submit="bonusManager.add()"><i class="fa fa-plus"/> Règle de calcul</button>
In the controller, define this.add = function() {... instead of $scope.add = function() {.... Because the keyword as will call a new BonusCtrl() under the hood.

If you use $scope than you don't need construction ControllerAs, just use
<div ng-controller="BonusCtrl">
and submit function ng-submit="add()"
Or if you want to use ControllerAs, than use "this":
<div ng-controller="BonusCtrl as bonusManager">
ng-submit="BonusCtrl.add()"
But in your controller have to be "this" instead of $scope:
`
this.add = function() {
`
Try it.

If you are using BonusCtrl as bonusManager then do as follows
Update bonusManager.add() in view and in controller write this.add instead of $scope.add() .
Otherwise just remove as bonusManager from ng -controller syntax .it will work fine.

Why is my angular binding read only in a bootstrap UI modal in an MVC5 project?

I am trying to pop up a modal to get some input, but the angular binding via ng-model seems to be read only. This is my modal markup:
<script type="text/ng-template" id="signatureWindow.html">
<div class="modal-header">
<h4 class="modal-title" id="myModalLabel">Signature Capture</h4>
</div>
<input type="text" width="100px" ng-model="theName" />
<div class="modal-footer">
<button ng-click="accept()" class="btn btn-primary">Accept</button>
<button ng-click="cancel()" class="btn btn-default">Cancel</button>
</div>
</script>
Then, I invoke this modal as follows:
$scope.getSignatureModal = function(signatureBase64) {
var modalInstance = $modal.open({
templateUrl: 'signatureWindow.html',
controller: 'SignatureModalController',
size: 'lg',
resolve: {
signatureData: function() {
return signatureBase64;
}
}
});
modalInstance.result.then(function(signatureData) {
alert('Signed');
signatureBase64 = signatureData;
}, function() {
alert('Canceled');
});
};
And the following controller code for the modal:
MlamAngularApp.controller('SignatureModalController', function($scope, $modalInstance, signatureData) {
$scope.base64 = signatureData;
$scope.thename = "NamesRus";
$scope.accept = function() {
debugger;
$modalInstance.close($scope.thename);
}
$scope.cancel = function() {
$modalInstance.dismiss('cancel');
}
});
The modal pops up as expected, and the input has the initial value "NamesRus", but when I close the modal, invoking accept in the modal controller, $scope.thename still has it's initial value, not any new value I type when the modal is active. What could be wrong here?
NOTE: At the debugger breakpoint in accept, no matter what I type in the modal's input, theName still has the initial assigned value.
MORE: My Plunker for this works fine. It's when in-place, in an ASP.NET MVC5 project, that I get the strange behaviour.

I think that you mix up two differents scopes.
If you want several variables to be passed to and retrieved from the modal you have to mention them:
in the resolve attribute
resolve: {modalData: function (){return {signatureData:$scope.base64,name:$scope.theName}}}
pass modalData as dependencie to your controller
MlamAngularApp.controller('SignatureModalController', function($scope, $modalInstance, modalData)
update the modal controller $scope with modalData
$scope.signatureData = modalData.signatureData;
$scope.name=modalData.name;
invoke
$modalInstance.close({signatureData:$scope.base64,name:$scope.theName})
reassign the original $scope with the result of promise
modalInstance.result.then(function (data) {
$scope.base64 = data.signatureData;
$scope.thename=data.name;
}
take a look at this plunker forked from ui-boostrap modal orginal example: http://plnkr.co/edit/whLSYt?p=info

Can't update $rootScope value after submit action

I'm a beginner with AngularJS. However, I can't update $rootScope value after submit a form, it's being returned as undefined.
The Controller:
app.controller('campaignCtrl', ['$scope', '$rootScope', function($scope, $rootScope) {
$scope.submit = function() {
$rootScope.campaign = this.campaign;
};
}]);
And the form:
<form class="holder" name="campaignForm" ng-submit="submit()" >
<div class="form-group" show-errors>
<label for="inputDate">Date</label>
<p class="help-block"><em>Ex: 12/10/2015</em></p>
<input type="date" class="form-control" name="inputDate" ng-model="campaign.date" id="inputDate" required>
</div>
<button type="submit" class="btn btn-lg btn-default pull-right">Submit</button>
</form>

I used your code and added a $watch on $rootScope.campaign and it worked great.
.controller('someController', function($scope, $rootScope) {
$scope.submit = function() {
$rootScope.campaign = $scope.campaign;
};
$rootScope.$watch('campaign', function(newVal, oldVal) {
if(newVal !== oldVal) {
console.log("New Val = ");
console.log(newVal);
}
});
});
JSFiddle
If you are looking for something that persists across a page refresh, that is not $rootScope. Look at something like this: AngualrJS: sustaining data on html refresh

Check this. Your code seems correct except that you are missing closing tag on the input
`http://jsfiddle.net/ashishmusale/2001cf6r/`

Try
$scope.submit = function() {
$rootScope.campaign = $scope.campaign;
};
EDIT:
Try removing type="submit" from your button. It could be that your handler doesn't get called because the browser handles the form submission automatically (although you could verify that by putting a log in that function).
<button class="btn btn-lg btn-default pull-right">Submit</button>
EDIT 2:
Per our conversation via comments: $rootScope doesn't persist across requests. You'll need to store it somewhere permanent (like local storage or a cookie) or pass it to the server and then back to the client if you want to hold on to that value. I bet if you add a log inside that $scope.submit function, it will have a value there.

Getting selected option in AngularJS

I am generating a thumbnail list of photos (using ng-repeat), and under each one of these photos I have two buttons, one to view more details and another to purchase.
I am finding a problem how to map the buttons. Basically I want that when a user clicks on the purchase button underneath Photo A, in the booking form (which is a different view), he/she will see the details pertaining to Photo A, rather than having the user select the photo again from some drop down. The list of photos is coming from a JSON string.
Mainly the difficulty I am finding is how to pass the details of which button was clicked to the booking view so that I would be able to display the details of the selected photo immediately.
I am new to AngularJS and am not sure if there is a simple way that can be done.
My HTML is this:
<div class="col-md-4 ng-scope" ng-repeat="photo in photos">
<div class="thumbnail">
<img src="{{photo.thumbnail}}" alt="{{photo.title}}">
<div class="caption">
<h4 class="ng-binding">{{photo.title}}</h4>
<p><button type="button" class="btn btn-default">Photographer</button><br ><button type="button" class="btn btn-default">Purchase</button></p>
</div>
</div>
Angular JS:
App JS
angular
.module('app', [
'ui.router'
])
.config(['$urlRouterProvider', '$stateProvider', function($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('photos', {
url: '/photos',
templateUrl: 'templates/photos.html',
controller: 'photosCtrl',
resolve: { photos: ['$http', function($http){
return $http.get('api/photos.json').then(function(response){
return response.data;
});
}]}
})
}]);
photosCtrl JS:
angular
.module('app')
.controller('photosCtrl', ['$scope', 'photos', function($scope, photos) {
$scope.photos = photos;
}]);

using ngClick directive is a good idea as #Ashesh suggested
Assuming the JSON containing your photos comes with a bunch of photo object, I'd rather add two functions to the scope of photosCtrl like this:
angular.module('app')
.controller('photosCtrl', ['$scope', 'photos', function($scope, photos) {
$scope.photos = photos;
$scope.showDetailsOf = function(photo) {
// photo argument is the actual object of which 'details' button was pressed
// coming from the ngRepeat in your template example
console.log('show details of ' + photo.title);
}
$scope.purchase = function(photo) {
// same as above
console.log('purchase ' + photo.title);
}
}]);
The template should look like this:
<button type="button" class="btn btn-default" ng-click="showDetailsOf(photo)">Details</button>
<button type="button" class="btn btn-default" ng-click="purchase(photo)">Purchase</button>
Furthermore you can factor this logic out to e.g. a photoService so that your controller won't contain business logic which is always preferable as both of your controller and the service can be covered by tests more easily, because you decouple them. Hope this helps.

Use ngClick:
<p><button type="button" class="btn btn-default" ng-click="photo.showPhotographer()">Photographer</button><br ><button type="button" class="btn btn-default" ng-click="photo.buy()">Purchase</button></p>
And ofcourse, photo.showPhotographer() etc. can do what you like them to do:
function Photo() { // the photo object
this.buy() {
// api call to buy with the id of the photo or window.navigate('buy_url?id=' + this.id), etc.
}
}
