Description

It seems like the data events (setData, changeData, getData) aren't triggering event handlers set with .live(). A minimal test case:

<html>
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    <script>
      $(document).ready(function() {
        var logger = function(evt, key, val) {
          $('#log').append('<p>' + evt.type + ':' + key + ':' + val + '</p>')
        };
        $('.container')
          .live('setData', logger)
          .live('getData', logger)
          .live('changeData', logger);
        
        $('#c1').data('a', 'foo');
        $('#c1').data('a', 'bar');
        $('#c1').data('a');
        $('body').append('<div class="container" id="c2"></div>');
        $('#c2').data('b', 1);
        $('#c2').data('b', 2);
        $('#c2').data('b');

        var expected = [
          "<p>setData:a:foo</p>",
          "<p>changeData:a:foo</p>",
          "<p>setData:a:bar</p>",
          "<p>changeData:a:bar</p>",
          "<p>getData:a:undefined</p>",
          "<p>setData:b:1</p>",
          "<p>changeData:b:2</p>",
          "<p>setData:b:2</p>",
          "<p>changeData:b:2</p>",
          "<p>getData:b:undefined</p>"
        ].join("");
      
        var actual = $('#log').html();
      
        if (actual == expected) {
          $('#message').append('Test passed');
        } else {
          $('#message').append('Test failed. Expected: ' + expected + ' Actual: ' + actual);
        }
      

      })
      
    </script>
  </head>
  <body>
    <div id="message"></div>
    <div class="container" id="c1"></div>
    <div id="log"></div>
  </body>
</html>

Note that in jQuery 1.4.3 these events no longer bubble (allowing them to bubble proved to be too costly in most applications). -- http://blog.jquery.com/2010/10/16/jquery-143-released/

Bubbling is required for .live or .delegate to work.

At the moment, the data events are lightly documented so it's not advisable to write code that depends on them or their current behavior.
