Look at the html code:

<!DOCTYPE html>
<html data-ng-app="App">
<head>
 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
 <script src="script2.js"></script>
</head>
<body data-ng-controller="AddStyleCtrl">
 
 <div>Choose Tags</div>
 <div>
  <div>You have choosen:</div>
  <hr>
  <label data-ng-repeat="selectedTag in selectedTags">
   (({{selectedTag}}))
  </label>
  <hr>
  <div data-ng-repeat="category in tagcategories">
   <div>{{ category.name }}</div>
   <div data-ng-repeat="tag in category.tags">
    <div>
     <input type="checkbox" id={{tag.id}} name="{{tag.name}}" ng-checked="isSelected(tag.id)" ng-click="updateSelection($event,tag.id)">
     {{ tag.name }}
    </div>
