Having trouble updating a scope more than once

I'm using angular with the ionic framework beta 1.

Here's my ng-repeat html:

   <a href="{{item.url}}" class="item item-avatar" ng-repeat="item in restocks | reverse" ng-if="!$first">
       <img src="https://server/sup-images/mobile/{{item.id}}.jpg">
       <h2>{{item.name}}</h2>
       <p>{{item.colors}}</p>
   </a>
  </div>

And here's my controllers.js, which fetches the data for the ng-repeat from a XHR.

   angular.module('restocks', ['ionic'])
  .service('APIservice', function($http) {

  var kAPI = {};

  API.Restocks = function() {
    return $http({
      method: 'GET', 
      url: 'https://myurl/api/restocks.php'
    });
  }

  return restockAPI;
})

  .filter('reverse', function() {
    //converts json to JS array and reverses it
      return function(input) {
        var out = []; 
        for(i in input){
          out.push(input[i]);
        }
        return out.reverse();
      }
    })

.controller('itemController', function($scope, APIservice) {
    $scope.restocks = [];
    $scope.sortorder = 'time';

    $scope.doRefresh = function() {
        $('#refresh').removeClass('ion-refresh');
        $('#refresh').addClass('ion-refreshing');
           restockAPIservice.Restocks().success(function (response) {
            //Dig into the responde to get the relevant data
            $scope.restocks = response;
            $('#refresh').removeClass('ion-refreshing');
            $('#refresh').addClass('ion-refresh');
        });
      }

      $scope.doRefresh();

  });

The data loads fine but I wish to implement a refresh button in my app that reloads the external json and updates the ng-repeat. When I call $scope.doRefresh(); more than once, I get this error in my JS console:
