title: Kendo Grid with custom popup editor using MultiSelect - can't get selected items in model
body: <p>So the title pretty much says it all. I'm trying to incorporate the new MultiSelect widget into a Grid's custom popup editor template.</p>
  
  <p>I'm using the Data Attribute Initialization method and reading the dropdown options from a remote dataSource. This is all working okay, but I can't get the values of the selected items into the model.</p>
  
  <p>When I save the row, an array of data is sent to the server representing the first data item selected in the MultiSelect, rather than a comma-separated list of selected values.</p>
  
  <p>Any ideas how I can get the MultiSelect value (list/array of selected values) into the grid model?</p>
  
  <p>Thanks</p>
  
  <p>Edit: I've now used a workaround, but I'd be interested to know if there's a 'proper way' to use MultiSelects with Grids.</p>
  
  <p>The workaround is to add something like this to the Grid's configuration:</p>
  
  <pre><code>save: function(e) { 
      e.model.items = $('#select_items').data("kendoMultiSelect").value();
  }
  </code></pre>
  
  <p>This is the relevant part of the popup editor template:</p>
  
  <pre><code>&lt;input name="select_items" id="select_items" data-value-field="id" 
  data-text-field="description" data-source="itemsDataSource" 
  data-role="multiselect" data-auto-bind="false" data-item-template="itemList"&gt;
  </code></pre>
  
  <p>I've not got <code>select_items</code> in the model definition: I'm using the workaround above to copy the MultiSelect's value to <code>items</code> which is in the model. This seems to work, I just don't know why it is necessary.</p>
