title: Change Icon on jQuery Mobile Collapsible Sets
body: <p>I'm working with jQuery Mobile for the first time and I'm having trouble accomplishing what seems like a simple change to the icons on a <a href="http://jquerymobile.com/test/docs/content/content-collapsible-set.html" rel="nofollow">collapsible set (accordion)</a>. </p>
  
  <p>I want to change the icon for each of the headings on a collapsible set to an up arrow for the expanded state and a down arrow for the collapsed state.</p>
  
  <p>I've created <a href="http://jsfiddle.net/HvMNL/8/" rel="nofollow">a Fiddle</a> that seems to have the same problem with code that I pretty much copied directly from the jQuery mobile site and modified a little.</p>
  
  <p>Any help or pointers on this would be much appreciated. Thanks!</p>
