title: Ajax callback function not being called when a dropkick styled dropdown has more than one item
body: <p>I have a aspx page that contains a number of dropkick styled dropdowns.
  Some dropdowns in the page have only one item while some dropdowns in the same page may have more than one item.
  Each drop down has an onchange event(javascript) that calls an 
  Ajax function when the user selects an item in the drop down.</p>
  
  <p>The Ajax function is called from the dropkick.js file  </p>
  
  <pre><code>if ($option.parents('.dk_container').siblings('select').attr('type') == "AttributeValue") {
  
      //for changing the details of a product when the product attribute is changed
       var selectedItemValue = ''; //the value of the current
       var dropDownName = '';
       selectedItemValue = parseInt($option.attr('data-dk-dropdown-value'));
       dropDownName = $option.parents('.dk_container').siblings('select').attr('name');
  
       /*javascript function that calls the Ajax function */
       ChangeProductDetails(selectedItemValue, dropDownName);
              } 
  </code></pre>
  
  <p>The problem is that when the user selects an item in a drop down containing multiple items
  the Ajax function is called but the Ajax callback function is not called.</p>
  
  <p>IF a drop down contains only one item then the Ajax callback function is called as expected.</p>
  
  <p>Thanks in advance for any tips</p>
  
  <p>Regards</p>
