title: Kendo grid sorting issue
body: <p>I've got it half working but it has 2 issues,</p>
  
  <p>1st while is does sort when set right (sortable: true but serverSorting: false) it will only sort the present page of results</p>
  
  <p>2nd with serverSorting: true it won't do any sorting but will post the parameters:-</p>
  
  <p>page    1
  pageSize    10
  skip    0
  sort[0][dir]    asc
  sort[0][field]  Ward
  take    10</p>
  
  <p>ofc in the controller json it doesn't pickup/understand it in that format</p>
  
  <pre><code>public JsonResult _List(Request request, int skip, int take)
  </code></pre>
  
  <p>or</p>
  
  <pre><code>public JsonResult _List(List&lt;SortDescription&gt; sort, int skip, int take)
  </code></pre>
  
  <p>both will have count = 1 when I click to sort a column but both have field/dir null even if I just try string field, string dir.</p>
  
  <p>So far as I can see I'm not correctly sending the sort data from the view to the controller but then I can't seem to find anywhere that it clearly indicates how it gets from point a to point b and is then implemented in the json.</p>
  
  <p>Anybody have any ideas or suggestions?</p>
