title: how do I make selectable or not selectable a kendo grid by a button
body: <p>I have a grid, with the selection mode enabled, in the grid definition</p>
  
  <pre><code>selectable: true
  </code></pre>
  
  <p>I need to make the grid not selectable, by a button. I tried this, but it isn't working:</p>
  
  <pre><code>$("#disableKendoGrid").click(function () {
      var grid = $("#myGrid").data("kendoGrid");
      grid.options.selectable = false;
      grid.refresh();
  });
  </code></pre>
