title: jQuery .prepend() Not Working
body: <p>and I am trying to prepend an option value from a select. I need the output to start with a capital "K". Here is my jQuery:</p>
  
  <pre><code>    $(document).ready(function () {
  $(".dialogbox").dialog({
      modal: true,
      autoOpen: false
  });
  $(".dropdown").change(function () {
      $(".dialogbox").dialog("open");
      $(".dialogbox").change("puff");
  });
  $('select.dropdown').change(function () {
      var capacityValue = $('select.dropdown').find(':selected').data('capacity').toUpperCase();   
      $('.dialogbox').val(capacityValue);
  });
  </code></pre>
  
  <p>});</p>
  
  <p>and here is my <a href="http://jsfiddle.net/jedimaster/qLFhj/6/" rel="nofollow">fiddle</a></p>
  
  <p>I've tried </p>
  
  <pre><code>$('.dialogbox').val(capacityValue).prepend( 'K' );
  </code></pre>
  
  <p>but that didn't seem to work. All the examples I've seen indicate that this should work. Thanks in advance for the help. </p>
