title: AngularJS and ng-repeat elements do not exist in DOM yet - getting NULL exepction
body: <p>So I am trying to use an external library function to create some manipulation in the DOM in one of my controllers that my ng-repeat is connected to. The problem is the following:</p>
  
  <p>I am calling that external function in my controller that adds elements to the ng-repeat array , which in term adds the new elements to the DOM. However, when I am inside the controller, the element does not exist yet, even though I have added it to the array. How can I bound an external function to be called once the element has actually been appended to the DOM, rather than when it was actually added to the array that controls the ng-repeat?</p>
  
  <p>I want to fire the event once the element has actually been created. Any suggestions?</p>
  
  <p>Let me know if you would like to see a fiddle of this idea.</p>
