title: JQuery Validation Plugin submitHandler doesnt work for me
body: <p>Hello i got the following issue my following code doesn't work for me and i cant figure out why. I hope you guys can help me.</p>
  
  <p>Edit: The submit handler simply doesn't get called. I don't even get the alert message. I wanted to disable the submit button till the form is validated. </p>
  
  <pre><code>    $('form').validate({
  
          onsubmit: true,
          debug: true,
          errorLabelContainer: "#errorBox",
          rules: {
              user_email: {
                  minlength: 4,
                  email: true,
                  required: true
              },
              user_textField: {
                  minlength: 3,
                  required: true
              },
              user_phone: {
                  required: true,
                  number: true,
                  minlength: 4
              },
              user_fax: {
                  number: true,
                  minlength: 4
              },
  
              user_plz: {
                  required: true,
                  number: true,
                  minlength: 5
              }
          },
          submitHandler: function (form) {
              $('form').find(":submit").attr("disabled", true).attr("value","Submitting...");
              alert("hie");
              form.submit();
          }
      }); 
  </code></pre>
  
  <p>I also got a submit button:</p>
  
  <pre><code>&lt;button class="btn btn-primary pull-right continuePaymentProcess" type="submit"&gt;Weiter&lt;/button&gt;
  </code></pre>
  
  <p>Best Regards Grandy</p>
