title: How to filter kendo grid with a column that contains multiselect - multiple values?
body: <p>I have a multiselect grid column same as onabai (awesome guy on so!) I need to put filter menu on that column.</p>
  
  <p><a href="http://onabai.wordpress.com/2013/07/17/kendoui-multiselect-in-a-grid-yes-we-can/" rel="nofollow">http://onabai.wordpress.com/2013/07/17/kendoui-multiselect-in-a-grid-yes-we-can/</a></p>
  
  <p>I have added custom filter on the multivalue column</p>
  
  <pre><code>  filterable: {
      ui: function(element) {
        element.kendoDropDownList({
          dataSource: [ "London", "Surat", "New York"]  //etc
        });
      }
  </code></pre>
  
  <p>The filter shows up on the grid column but the filter does not filter. 
  I guess, I need to somehow capture the filter change event and filter data source based on value selected.</p>
  
  <p>Any pointers?</p>
  
  <p>Thanks.</p>
