title: Jquery-mobile radio is checked but not displayed
body: <p>Javascript decides which button is checked when the page loads. The code successfully detects this but the 'checked' button doesn't display.</p>
  
  <p>I have added .checkboxradio("refresh") to the radio group and to the individual radiobutton to no avail. A demo is here: <a href="http://jsfiddle.net/mckennatim/a9jx9/" rel="nofollow">http://jsfiddle.net/mckennatim/a9jx9/</a></p>
  
  <p>.button("refresh") causes an error.</p>
