javascript - Angular $http result sort and bind to view? -

i'm trying render results data pulled successful $http.get, push through 2 or 3 functions sort/concat/filter data few different ways, , store rest of apps duration.

i have following service:

myapp.service('versionservice', function($http, $log, $q) {      var self = this;      this.issues = {         all: []     };      this.versions = {         all: [],         byname: [],         byid: []     };       var query = {};     query.jql = "fixversion in unreleasedversions() order fixversion asc";      $http({         url: '/search/versions',         method: 'post',         //cache: true,         data: query     })         .then(function (response) {             //console.log(response.data.issues);             for(var = 0; < response.data.issues.length; i++) {                 self.issues.all.push(response.data.issues[i]);                 for(var j = 0; j < response.data.issues[i].fields.fixversions.length; j++) {                     self.versions.all.push(response.data.issues[i].fields.fixversions[j]);                 }             }         }, function (err) {             console.log(err);         });  }); 

my controller:

 myapp.controller('filteredcontroller', function($scope, $http, $log, versionservice) {      $scope.isactive = function(version) {         return version == versionservice.selectedv;     };      $scope.issues = {         all: versionservice.issues.all     };      $scope.versions = {         all: versionservice.versions.all,         byname: versionservice.versions.byname,         byid: versionservice.versions.byid     };  }); 

no matter how try it, if put sort/filter/concat on this.versions.byname in controller, gives blank array return. i'm guessing because sort/filter/concat running before http.get , loops finish? means view doesn't show if try pull vesions.byname/id/

how run functions sort/filter/concat data, put in other arrays in versions object, have binded view?

i trying use following function:

var versionsbyname = function() {      var prev = null;      self.versions.byname = self.versions.all         .concat()         .sort()         .filter(function (i) {             if (i.name !== prev.name) {                 prev = i;                 return true;             }         })  }; 

no matter put it, or if make iife, won't work.
