title: Error: Syntax error, unrecognized expression: jqmData
body: <p>Trying to do a simple selection like so: </p>
  
  <p><code>
  $('div:jqmData(role=collapsible)')
  </code></p>
  
  <p>But I get the follwing error (from Chrome console):</p>
  
  <p><code>Uncaught Error: Syntax error, unrecognized expression: jqmData</code></p>
  
  <p>My understanding from <a href="http://jquerymobile.com/demos/1.1.1/docs/api/methods.html" rel="nofollow">http://jquerymobile.com/demos/1.1.1/docs/api/methods.html</a> is that one should use the <code>:jqmData</code> selector, but it doesn't seem to work. Or I'm doing it wrong. Either way... ideas?</p>
