title: jQuery.validate.js onkeyup = true error
body: <p>With my jquery validation configuration, I get the following error when setting onkeyup to true. It works if I set it to false, but I don't get validation feedback until I blur the field, and I'm looking to get validation on each keyup:</p>
  
  <pre><code>$("#signupForm").validate({
          onkeyup: true,        
          onclick: false
          // rules omitted for brevity
      }
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>TypeError: validator.settings[eventType].call is not a function
  validator.settings[eventType].call(validator, this[0], event);
  jquery.validate.js line 391
  </code></pre>
