title: jQuery Mobile checkbox refresh not working
body: <p>I'm trying to change the state of my jQuery Mobile checkboxes using the following code:</p>
  <pre><code>$('#_inputcb_Q801').prop('checked', false);
  </code></pre>
  <p>I also found the following solution on jQuery Mobile:</p>
  <pre><code>$('#_inputcb_Q801').prop('checked', false).checkboxradio('refresh');
  </code></pre>
  <p>but it gives this error:</p>
  <blockquote>
  <p>Runtime-error Microsoft JScript: cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'</p>
  </blockquote>
  <p>How can I solve the problem ?</p>
