title: $watch not working inside Angular Modal
body: <p>I'm trying to put a $watch on a radio button inside <a href="http://angular-ui.github.io/bootstrap/" rel="nofollow">AngularJS Modal</a>. However $watch is not working inside modal for any value changes.</p>
  
  <p>If I try to put the radio buttons outside modal, the $watch works perfectly fine.</p>

  <p>In the above plunkr, if you click on Open me and select upper 2 radio buttons (me, you) $watch is not fired and in turn u cant see the alert with the value.</p>
  
  <p>However if you click on radio buttons in the main page (i.e. Outside window) $watch works perfectly fine and throws alert message.</p>
  
  <p>Does anyone have a workaround for this issue? Thanks</p>
