title: How to refresh submitHandler in jQuery Validation
body: <p>I'v got a problem with jQuery Validation plugin.
  When I defined custom submitHandler, it's stored after first validation run.
  I'm using submitHandler to send the Object via AJAX request, but when the object is changed after event trigger, it wont change in submit handler function.
  Is there any way to refresh submit handler after each event trigger?</p>
  
  <p>My code</p>
  
  <pre><code>$('.request-telephone-form-submit').click(function(){  
      var thisForm = $(this).closest('form');
  
      var postVars = new Object();
      postVars.name = $('.request-name').val();
      postVars.phone = $('.request-phone').val();
  
      thisForm.closest('form').validate({
          rules:
          {
              Name: {
                  required: true,
  
              },
              Telephone: {
                  required: true,
  
              }
          },
          submitHandler: function(){
              $.ajax({
                  type: 'POST',
                  url: '...',
                  data : postVars,
                  success : function(response) {                      
  
                  }
              });
  
          }
  
      })
  
  });
  </code></pre>
