title: jQuery ajaxForm "h is undefined" problem
body: <p>I have a form that is brought up in a ajaxed modal which I am using for updating user details.  When the modal loads I call a js function:</p>
  
  <pre><code>teamCreate: function() {
  $j("#step1,form#createEditTeam").show();
  $j("#step2").hide();
  var options = {
   type: "get",
   dataType: 'json',
       beforeSubmit:  before,  // pre-submit callback 
       success:       success  // post-submit callback
    };
  $j("form#createEditTeam").ajaxForm(options);
  
  function before(formData, jqForm, options){ 
   var valid = $j("form#createEditTeam").valid();
   if (valid === true) {
    $j(".blockMsg").block({ message: $j('#panelLoader') });
        return true; // submit the form
   } else {
    $j("form#createEditTeam").validate();
    return false; // prevent form from submitting
   }
  };
  
  function success(data){
   if (data.status == "success") {
    $j(".blockMsg").unblock();
   } else {
    //
  }
  };
  
  function error(xhr, ajaxOptions, thrownError){
  alert("Error code: " + xhr.statusText);
   };
  }
  </code></pre>
  
  <p>This works just fine when I first submit the form, regardless how many times the modal is opened and closed.  However, if I submit the form and then open the modal again and try to submit the form again I get a js error:</p>
  
  <p><code>h is undefined</code></p>
