List with array-data from database

Hey guys,

i get an array like that from my database request.

groups: Array[7]
0: Object
add_date: "02.04.2015"
categorie: "Outdoor"
gm_status: 1
group_ID: 9
groupadmin_ID: 1
groupadmin_forename: "André"
groupadmin_surname: "Driesel"
titel: "TEST3"
year: 2015
__proto__: Object
1: Object
2: Object
3: Object ...

For testing i want to display that like a normal list and so i used the chat-example from the ionic standard.
Here the code from the tab-groups.html:

<ion-view view-title="Gruppen">
      <ion-item class="item-remove-animate item-avatar item-icon-right" ng-repeat="group in groups" type="item-text-wrap" href="#/tab/groups/{{}}">
        <p>{{group.year}} {{group.categorie}} {{group.titel}}</p>
        <i class="icon ion-chevron-right icon-accessory"></i>
        <ion-option-button class="button-assertive" >

Do i have to build an factory for that? Actually i load this array via the controller, like that:

.controller('GroupsCtrl', function($scope, $http) {
 loadGroups(); // Load all available tasks
 function loadGroups(){
  console.log("request successfull")
  $scope.Groups = data;
