AngularJS ng-repeat filter by specific ID from JSON

I cant seem to make this work.
I've been trying to filter a JSON file by specific ID then iterate using ng-repeat.

here's what I've tried

here's the button trigger:

<a href="#/compare-details"><button class="viewDetails" ng-click="passID(11,02,00)" type="button">test button</button></a>


after passing the 3 id parameters, it goes to my controller:

var newData;
angular.module('handsetExplorerModule')
.controller("compareDetailsController", ['$scope','compareDetailsService', function($scope, compareDetailsService) {

compareDetailsService.getHandsetList()
.then(
function(data){

$scope.passID = function(id1,id2,id3){

for(int i=0; i<data.phones.length; i++){
if(data.phones[i].id == id1 || data.phones[i].id == id2 || data.phones[i].id == id3){
newData += data.phones[i];
}
}
}
},
function(error){
//todo: handle error
}
);

$scope.phoneContent = newData;

}]);


JSON file came from service:

angular.module('handsetExplorerModule')
.factory('compareDetailsService', ['$http','$q', function($http, $q) {
var service = {
};
service.getHandsetList = function(){
var deferred = $q.defer();
$http.get("./data/compareJSON.json").then(function(response) {
deferred.resolve(response.data);
},
function(response){
deferred.reject("ERROR: Unable to get handsetList data");
}
);
return deferred.promise;
};

return service;
}]);


and my ng-repeat

<div id="divContent">
<div>
<table id="Content" ng-repeat="x in phoneContent">
<tr>
<td class="one">
<table>
<tr>
<td><img class="contImage" ng-src="{{x.image}}" ng-alt="{{x.name}}" /></td>
<td class="textAlign">{{x.name}} <button class="viewDetails" ng-click="viewDetails(x.id)" type="button">VIEW DETAILS</button></td>
</table>
</td>
<td class="two">{{x.size}}</td>
<td class="one">{{x.storage}}</td>
<td class="two">{{x.camera}}</td>
<td class="one">{{x.battery}}</td>
<td class="two">{{x.network}}</td>
<td class="one">{{x.sim}}</td>
</tr>
</table>
</div>
</div>

please check refactored a little bit plunker: http://plnkr.co/edit/paPSj8Dm4Z1RCbFw9FmS?p=preview

BTW, $http service by its self is a Promise, so no need to use $q service, just return $http:

myApp.factory('compareDetailsService', ['$http', function($http) {
  return {
    getHandsetList: function(){
      return $http.get("data.json");
    }
  };
}]);

there is a very similar tutorial, you should look at: https://docs.angularjs.org/tutorial/step_00
