title: jQuery .change() not firing?
body: <p>I've got a jQuery .change() event, to recognise when a radio button is selected / changed.</p>
  
  <p>Here's the radio button code:</p>
  
  <pre><code>&lt;input type="radio" name="joint" value="0" class="who" data-entity="me"/&gt;
  &lt;input type="radio" name="joint" value="1" class="who" data-entity="me and partner"/&gt;
  </code></pre>
  
  <p>My javascript to detect the change is as such:</p>
  
  <pre><code>$('input[name=joint]').bind('change', function(){
      alert('changed');
      $('.jointWho').html('Cover for '+$('option:selected',this).data('entity'));
  });
  </code></pre>
  
  <p>However, when I select/change the radio button, the even doesn't fire, and I don't see an alert.</p>
  
  <p>Any ideas?</p>
