javascript - angular js - unable to access objects pushed to array in controller -

here controller

angular.module("app").controller('mycontroller', ['$scope', '$filter','$rootscope','contentservice','$location','$anchorscroll', function ($scope, $filter,$rootscope,contentservice,$location,$anchorscroll) {  $scope.searchcontents = [] ;  var filterlist = function (list, keyword) {     return $filter('filter')(list, keyword); };  var addtosearchcontents = function (list,type){     _.each(list,function(item){         item.type = type;         $scope.searchcontents.push(item);     });      };  $scope.init = function(){     var str = $location.absurl();     $scope.searchkeyword = str.substring(str.indexof("=") + 1,str.length);      !_.isempty($scope.searchkeyword)     {         // songs         contentservice.getallsongs().then(function (result) {             var filteredsongs = filterlist(result.data.songs, $scope.searchkeyword);             addtosearchcontents(filteredsongs,"song");         });          // people         contentservice.getallpeople().then(function (result) {             var filteredpeople = filterlist(result.data.people, $scope.searchkeyword);             addtosearchcontents(filteredpeople,"people");         });                     _.each($scope.searchcontents,function(item){               alert("item -> "+item.type);         });     } };  $scope.init();  }]); 

items(objects) added variable $scope.searchcontents in addtosearchcontents if try access/iterate after objects pushed $scope.searchcontents _.each seems null. can access contents in html page ng-repeat not in controller. puzzled, missing something.

yet variant, $q.all:

$q.all([     // songs     contentservice.getallsongs().then(function (result) {         var filteredsongs = filterlist(result.data.songs, $scope.searchkeyword);         addtosearchcontents(filteredsongs,"song");     }),      // people     contentservice.getallpeople().then(function (result) {         var filteredpeople = filterlist(result.data.people, $scope.searchkeyword);         addtosearchcontents(filteredpeople,"people");     })]).then(function(){                  // here items added can iterate         _.each($scope.searchcontents,function(item){             alert("item -> "+item.type);         });     });
