title: Zynga Scroller "Completed" Method?
body: <p>I'm using Zynga Scroller (
  <a href="https://github.com/zynga/scroller" rel="nofollow">https://github.com/zynga/scroller</a>) to scroll a list and snap to middle. I need something to hook onto when the scrolling is complete to show an article based on that list item. My question is there a way to use "completed" (which is in the core)?</p>
