title: simple hierarchy with jQuery mobile nested list + knockout.js
body: <p>I am trying to make a simple nested list (jQuery Mobile) get filled by knockout.js
    The data is a simple JSON hierachy.</p>
  
  <p>Please check <a href="http://jsfiddle.net/RYLve/" rel="nofollow">http://jsfiddle.net/RYLve/</a></p>
  
  <p>The parent item is displayed but it is not navigable.
    What's wrong?</p>
  
  <p>Thanks!</p>
