title: Handling moving of item across lists in angular-ui sortable?
body: <p>I am using <a href="https://github.com/angular-ui/ui-sortable/tree/angular1.2">angular-ui sortable version 1.2</a></p>
  
  <p>I want to handle the move of an item from one list to another, and update the back-end accordingly.</p>
  
  <p>jquery-ui-sortable defines a bunch of events, including the <a href="http://api.jqueryui.com/sortable/#event-receive">receive event</a></p>
  
  <p>From within that event handler, I cannot find a way to access the angular model item which was moved, and its new parent list.</p>
  
  <p>See this <a href="http://codepen.io/anon/pen/Lfgay">codepen sample</a>.
  You can see that I can access the item via the <code>scope()</code> in the <code>update</code> event, but not in the <code>receive</code> event.</p>
  
  <p>Any suggestions for a way to handle these moves? either via the <code>receive</code> event or otherwise?</p>
