javascript - AngularJS not displaying JSON response in view -

updated requested more info:

i have controller calls web method , want returned json binded variable in controller called applications. alert displays json correctly see nothing in view.

note have tried $scope , 'this' in controller manual data , 'this' worked why have use instead of $scope below.

app.controller('appscontroller', function ($http, $scope) { $http.post('/webmethod/dostuff', {}).  success(function (data, status, headers, config) {      alert(data);      this.applications = data;  }) } 

my view this

<div class="container" ng-controller="appscontroller appctrl"> <div class="row" ng-repeat="application in appctrl.applications">  <div class="col-xs-6 applicationname" ng-click="appctrl.expand($index)">{{application.name}}</div> </div></div> 

json like

[ {     name: "application 1",     alerts: "2",     status: "red",     notifications:  [         {             header: "notification header 1",             updatetype: "new",             message: "hello world",             starttime: "11:00",             endtime: "12:00"         }                   ],     expanded: false }] 

this not expect be. try this:

app.controller('appscontroller', function ($http, $scope) {   var self = this;   $http.post('/webmethod/dostuff', {}).    success(function (data, status, headers, config) {        alert(data);        //or can use $scope.applications = data; instead         self.applications = data;    }) } 

see how "this" keyword work? explanation of this in javascript.
