title: Custom filter for Kendo UI Mobile listview?
body: <p>Is it possible to apply a custom function to filter a Kendo UI Mobile listview? In particular I want to filter by two properties of my JS objects, not only by a single property.</p>
  
  <p>My current code:</p>
  
  <pre><code>$("#myListView").kendoMobileListView({
      dataSource: 
          [
              { id: 1, firstName: 'Mike', lastName: 'Morris'},
              { id: 2, firstName: 'Steve', lastName: 'Bitner'}
          ], // faked data
      template: $("#myTemplate").html(),
      filterable: {
          field: "firstName", // should be firstName+lastName
          operator: "contains",
          placeholder: "Name...",
          ignoreCase: true
      }
  });
  </code></pre>
  
  <p>In this particular example I want to filter by firstName and lastName, but the <code>filterable.field</code> option of the listview only allows one property and not two nor a custom filter function.</p>
