How to select and deselect an div / button in angularJs?

I am trying to make items not in list but in div and if an item is clicked, the div will be in different colors and the item will be added into a column but if the item is clicked again, the item will changed to original color and in the column the item will be gone. I just can't think how to do it in angular way. I came to another option to be able to add in the column and to remove the item, there's a remove button but I am still curious how the select and deselect can be done.
This is what I have in my html (ignore my btn btn-primary classes I was using button to give it a try in the first place)
<!--Select App Features-->
<div class="panel-heading" ng-controller="FeaturesController as featuresCtrl">
<h1 class="text-center">App Features</h1>
<div class="text-center">
<div ng-repeat="app in featuresCtrl.apps" class="btn btn-primary platform-btn-style" ng-click="featuresCtrl.addPrices(app.name, app.price)">{{ app.name }}</div><br>
</div>
<div>
<table class="table table-striped table-hover">
<thead>
<tr>
<th>Device Added</th>
<th>Device Price</th>
<th></th>
</tr>
</thead>
<tr ng-repeat="appList in featuresCtrl.listAppPrices">
<td>{{ appList.name }}</td>
<td>{{ appList.price }}</td>
<td><button class="btn btn-default" ng-click="featuresCtrl.remove($index)">Remove</button></td>
</tr>
</table>
<div>Total : {{ featuresCtrl.totalAppPrice() }}</div>
</div>
</div><!-- end select app features / FeaturesController-->
My controller in js
//Controller for app features
app.controller("FeaturesController", function(){
this.apps = features;
this.listAppPrices = [];
// add name and price into the new array which is used to show in the table
this.addPrices = function(name, price){
//Checks if the exact name, price property exists in the array and return boolean
var found = this.listAppPrices.some(function (e){
console.log(e.name);
return ((e.name === name) && (e.price === price)) ;
});
//If found not true then push the new values into the array
if(!found){
this.listAppPrices.push({name: name, price: price});
}
};
// adds all the prices of the array which gives the total
this.totalAppPrice = function(){
var total = 0;
for(var i = 0; i < this.listAppPrices.length; i++){
total += this.listAppPrices[i].price;
}
return total;
};
// remove the whole object in the array when remove is clicked
this.remove = function(index) {
this.listAppPrices.splice(index, 1);
};
});
I kind of having the idea of how this can be done but I just can't think of the code to write it.
P.S. the codes are simple, I just learned it in code school and wanted to created something for fun to educate myself. Thanks in advance people

I haven't added the functionality of remove button.I also haven't count the totalAppPrice. Otherwise your problem is solved :) .

Any help would be much appreciated.

You missed to inject $modal dependency inside postsCtrl controller
app.controller('postsCtrl', function ($scope, $log, $http, $timeout, Data, $modal) {
Make sure you have injected particular dependency before getting
access to it. Assuming you have already added ui.bootstrap module
dependency too.
UPDATE
If you are using latest version of angular ui bootstrap which is 0.14.X would need to inject $uibModal instead of $modal. As they rename all boostrap directive and serviec name prepends with uib prefix.
Same thing will happen with $modalInstance dependency, which need to change to $uibModalInstance

AngularJS's ng-table reload not working

I have been googling and none of the solutions have worked for me. I have an AngularJS page that simply has a small set of data with no paganation or anything and I just want to be able to delete an entry and have the table update. However my call to $scope.tableParams.reload() just doesn't do anything.
Here is my controller:
app.controller('viewVersion', ['$scope', '$filter', '$RestService', 'NgTableParams', '$cookies', '$routeParams', '$q', 'Flash', '$location', function($scope, $RestService, NgTableParams, $cookies, $routeParams, $q, Flash, $location) {
$scope.version = {id:null, version:null, comment:null, states:[]};
$scope.permissions=$cookies.get('permissions');
var promise = $RestService.StateList(); //Get the list of states to use to map state ids to their names (BOI, REQ, etc).
promise.success(function(data) {
$scope.stateList = data;
});
promise.then(function(){
var inprom = $RestService.GetVer($routeParams.verid); //Get the version from the API given the version id.
inprom.success(function(data){
data.forEach(function(ver) {
$scope.version['id'] = ver.id;
$scope.version['version'] =ver.version;
$scope.version['platform'] =ver.platform;
$scope.version['comment'] = ver.comment;
if (ver.state!=null) {
var state_info = _.where($scope.stateList, {state_id:ver.state})[0];
$scope.version.states.push({state:state_info.state_name, state_id:ver.state, launch:ver.launch});
}
});
})
inprom.error(function(errorData) {
$cookies.set('flash_message', "Error getting version with ID "+$routeParams.verid);
});
inprom.then(function() {
$scope.tableParams = new NgTableParams({
sorting: { launch: "desc" }
}, {
counts:[],
total: $scope.version.states.length,
filterDelay: 0,
dataset: angular.copy($scope.version.states)
});
});
});
$scope.delete = function(row) {
_.remove($scope.tableParams.settings().dataset, function(item) {
return row.state_id === item.state_id;
});
$scope.tableParams.total($scope.tableParams.settings().dataset.length);
$scope.tableParams.reload();
};
}]);
And the matching html:
<table ng-table="tableParams" class="table table-bordered table-hover table-condensed editable-table" ng-form="tableForm">
<tr ng-repeat="state in version.states" ng-form="stateForm">
<td title="'State'" sortable="'state'">{{state.state}}</td>
<td title="'Launch Date'" sortable="'launch'" ng-switch="state.isEditing" ng-form="launch">
<span ng-switch-default class="editable-text">{{state.launch | date:'medium':'UTC'}}</span>
<div class="controls" ng-class="stateForm.$invalid ? 'has-error' : ''" ng-switch-when="true">
<input type="text" name="name" ng-model="state.launch" class="editable-input form-control input-sm" required />
<p ng-show="stateForm.$invalid && !stateForm.$pristine" class="help-block">Enter a valid date and time.</p>
</div>
</td>
<td>
<button class="btn btn-primary btn-sm" ng-show="permissions.indexOf('admin') > -1" ng-click="save(state, stateForm)" ng-if="state.isEditing" ng-disabled="stateForm.$pristine || stateForm.$invalid"><span class="glyphicon glyphicon-ok"></span></button>
<button class="btn btn-default btn-sm" ng-show="permissions.indexOf('admin') > -1" ng-click="cancel(state, stateForm)" ng-if="state.isEditing"><span class="glyphicon glyphicon-remove"></span></button>
<button class="btn btn-default btn-sm" ng-show="permissions.indexOf('admin') > -1" ng-click="state.isEditing = true" ng-if="!state.isEditing"><span class="glyphicon glyphicon-pencil"></span></button>
<button class="btn btn-danger btn-sm" ng-show="permissions.indexOf('admin') > -1" ng-click="delete(state)" ng-if="!state.isEditing"><span class="glyphicon glyphicon-trash"></span></button>
</td>
</tr>
</table>
Any help would be very appreciated. Thanks!

Your rows are coming directly from your data,
<tr ng-repeat="state in version.states">
...but your delete function is removing rows from ng-table's copy of the data:
$scope.delete = function(row) {
_.remove($scope.tableParams.settings().dataset, function(item) {
return row.state_id === item.state_id;
});
$scope.tableParams.total($scope.tableParams.settings().dataset.length);
$scope.tableParams.reload();
};
You want to pull your rows from ng-table's copy instead:
<tr ng-repeat="state in $data">

AngularJS: table edit data + update server

I have managed to create a table using AngularJS. In this table I show products from my datbase which can be filtered on category or some other keywords. Now the user should be able to alter this data in this table to update the data in the database.
AngularJS
categorieFilter = angular.module("categorieFilter", [])
categorieFilter.controller("catFilter", ["$scope", "store", function($scope, store){
$scope.search = "";
$scope.products = [];
$scope.categories = [];
store.getCategories().then(function(data){
$scope.categories = data;
})
store.getProducts().then(function(data){
$scope.products = data;
})
$scope.filterProductsByCats = function(category){
$scope.search = category;
};
}])
categorieFilter.factory('store', function($http, $q){
function _getCategory (){
var deferred = $q.defer();
$http.get('api/categories').success(function (data) {
deferred.resolve(data);
})
return deferred.promise;
}
function _getProducts (){
var deferred = $q.defer();
var prods = [];
$http.get('api/products').success(function (data) {
for(var i = 0;i<data.length;i++)
{
prods[i] = {name: data[i][0], category: data[i][2], price: data[i][1]};
}
deferred.resolve(prods);
})
return deferred.promise;
}
return {
getCategories: _getCategory,
getProducts : _getProducts
};
});
HTML table
<div ng-app="categorieFilter" ng-cloak="" ng-controller="catFilter">
<div class="input-group">
<input type="text" name="table_search" class="form-control input-sm pull-right" ng-model="search" placeholder="Search"/>
<div class="input-group-btn">

</button>
</div>
</div>
<div>
<input type="submit" class="btn btn-success" style="margin:10px; width:30%;" ng-repeat="cat in categories" ng-click="filterProductsByCats(cat.categoryName)" value="{{cat.categoryName}}">
</div>
<table class="table table-hover">
<tr style="background-color:#ddd;">
<th colspan="4" style="text-align:left; font-size:16px;"> Category </th>
<th colspan="4" style="text-align:left; font-size:16px;"> Product </th>

<td colspan="4">{{product.category}}</td>
<td colspan="4">{{product.name}}</td>

Any ideas or reccomendations to get this done?

Angular.js ng-click event not firing

I'm new to Angular JS, and I'm trying to implement a page to display, add, edit and delete objects from a REST API. I have functions to add, edit and delete items bound to ng-click, but the edit and delete events are not firing. The only difference between the add and edit/delete bindings seems to be that the edit/delete ng-clicks are inside an ng-repeat.
JavaScript code:
process_errors = function(rejection) {
// Error processing code
}
var exampleApp = angular.module('exampleApp', ['ngResource']);
exampleApp.factory('Example', ['$resource', function($resource) {
return $resource('/api/v1/example/:example_id', {example_id:'#id'});
}]);
exampleApp.config(['$httpProvider', function($httpProvider) {
$httpProvider.defaults.headers.common['X-CSRFToken'] = $.cookie('csrftoken');
}]);
exampleApp.controller('exampleListCtrl', ['$scope', 'Example',
function($scope, Example) {
$scope.examples = Example.query();
$scope.newExample = new Example();
$scope.add = function() {
$scope.newExample.$save().then(function(result){
$scope.examples.push(result);
}).then(function() {
$scope.newExample = new Example();
}, process_errors);
}
$scope.editExample = function(example) {
console.log('editing');
var idx = $scope.examples.indexOf(example);
$scope.examples[idx].$save().then(function(result) {
}, function(rejection) {
process_errors(rejection);
$scope.editMode = true;
});
}
$scope.deleteExample = function(example) {
console.log('deletion');
example.$delete().then(function(){
var idx = $scope.examples.indexOf(example);
$scope.examples.splice(idx, 1);
});
}
}]);
HTML:
<div id="content-container" ng-app="exampleApp">
<table class="table table-striped" ng-controller="exampleListCtrl">
<thead>
<!-- Table headers -->
</thead>
<tbody>
<tr>
<form class="form-inline" role="form">
<td><input type="text" class="form-control" ng-model="newExample.start_date" placeholder="2013-11-25"></input></td>
<!-- more fields in the same format -->
<td><button class="btn btn-primary" ng-click="add()">Add</button></td>
</form>
</tr>
</tbody>
<tbody>
<tr ng-repeat="example in examples">
<form class="form-inline" role="form">
<td>
<span ng-hide="editMode">{{example.start_date}}</span>
<input ng-show="editMode" type="text" class="form-control" ng-model="example.start_date" value="{{example.start_date}}"></input>
</td>
<!-- more fields in the same format -->
<td>
<button ng-hide='editMode' class="btn btn-default" ng-click="editMode = true;">Edit</button>
<button ng-show='editMode' class="btn btn-primary" ng-click="editExample(example); editMode = false">Save</button>
</td>
<td><button class="btn btn-danger" ng-click="deleteExample(example)"><span class="glyphicon glyphicon-remove"></span></td>
</form>
</tr>
<tbody>
</table>
</div>
I've also tried binding the functions to $parent.editExample(example).
