title: jQuery validation: Custom rule not called
body: <p>Here is my simple validation code for testing:</p>
  
  <pre><code>    jQuery.validator.addMethod("oneTypeChecked", function (value, element) {
          return false; //$(':checkbox:checked') &gt; 0
      }, "Check one or more type");
  
      $("#RequestCreateForm").validate({
          rules: {
              ChkBoxType1: { oneTypeChecked: true }
          }
      });
  </code></pre>
  
  <p>But my method oneTypeChecked is never called when I submit form.
  Why?</p>
  
  <p>Here is my HTML code:</p>
  
  <pre><code>&lt;div class="editor-field"&gt;
      &lt;input type="checkbox" id="ChkBoxType2" name="requestTypeIds2" value="2"&gt;Type 2     
      &lt;input type="checkbox" id="ChkBoxType1" name="requestTypeIds1" value="1"&gt;Type 1        
      &lt;input type="checkbox" id="ChkBoxType3" name="requestTypeIds3" value="3"&gt;Type 3
  &lt;/div&gt;
  </code></pre>
  
  <p>Thank you very much!</p>
