title: data-binding doesn't work after using "appendChild()" to add new element
body: <p>when i write like this, angular works: </p>
  
  <pre><code>&lt;html ng-app="mptmanager" class="ng-scope"&gt;
       &lt;body&gt;
           &lt;input ng-model = "test" /&gt;&lt;br /&gt;
           {{test}}
       &lt;/body&gt;
   &lt;/html&gt;
   &lt;script src="js/angular.min.js"&gt;&lt;/script&gt;
   &lt;script src="angular/angularModules.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>but when i run JS code like this:</p>
  
  <pre><code>var temp = document.createElement('div');
  temp.innerHTML = '&lt;input ng-model = "test2"&gt;&lt;br /&gt;{{test2}}';
  document.body.appendChild(temp);
  </code></pre>
  
  <p>angular has no effect to the new element, so i can only see "{{test2}}" on my page...</p>
  
  <p>how can i make angular work when i try to add or change some element on my page with JS?</p>
