title: jQuery validate submitHandler triggers validation
body: <p>When using the jQuery submitHandler method, I'm posting the form data via ajax to the server. On success, another method is called that resizes a popup and notifies the user its all complete.</p>
  
  <p>My problem is however, whilst posting the data, the form is getting validated again causing undesired effects.</p>
  
  <p>My understanding is submitHandler shouldn't trigger the validation again?</p>
  
  <pre><code>submitHandler: function(form) {
      console.log('test');
  }
  </code></pre>
  
  <p>In this instance, 'test' is being logged to the console, but the validation is being run once again (in this case, a server side validity check on an email address field).</p>
  
  <p>I'm using a button type submit as the form element. Do I need to prevent defaults or something similar?</p>
