title: jQueryMobile Checkbox fires change event for entire controlgroup
body: <p>I have a set of checkboxes setup in a series of div fieldcontain + fieldset controlgroups. They are grouped by topic with 12 main topics and 2-5 sub-topic under each.</p>
  
  <p>When I "change" a checkbox, it fires the change event for the entire controlgroup. If I remove the control group fieldset, it fires the change event (when tapped) for the entire list, whether I use input[name="checkbox_name"] or input.checkbox-class.</p>
  
  <p>How do I get the change for <em>just</em> the actual checkbox changed (from unchecked to checked or checked to unchecked)?</p>
