title: Kendo Grid local datasource causing TypeError r is undefined
body: <p>I am creating a kendo grid that uses local datasouce with this code.</p>
  
  <pre><code>var jsondata = [{
      abc: "Star Wars: A New Hope",
      def: 1977,
      ghi: 1977,
      jkl: 1977,
      mno: 1977,
      pqr: 1977
  }];
  
  $("div#@code").Grid({
      dataSource: {
          data: jsondata,
          schema: {
              model: {
                  fields: {
                      abc: { type: "string" },
                      def: { type: "number" },
                      ghi: { type: "number" },
                      jkl: { type: "number" },
                      mno: { type: "number" },
                      pqr: { type: "number" }
                  }
              }
          },
          pageSize: 20
      },
      height: 430,
      scrollable: true,
      sortable: true,
      filterable: true,
      pageable: {
          input: true,
          numeric: false
      },
      autoBind: true,
      columns: [
              { title: 'abc', field: 'abc' },
              { title: 'def', field: 'def' },
              { title: 'ghi', field: 'ghi' },
              { title: 'jkl', field: 'jkl' },
              { title: 'mno', field: 'mno' },
              { title: 'pqr', field: 'pqr' },
         ],
      });
  </code></pre>
  
  <p>The .Grid is an extension of the kendoGrid function, because I needed to custom the grid. Inside that function I call</p>
  
  <pre><code>//     Initialize the grid.
  kendo.ui.Grid.fn.init.call(that, element, options);
  </code></pre>
  
  <p>When I tested the code, the browser is giving me TypeError r is undefined. Which after I did my research, it is about the kendo grid trying to call dataSource update method that of course does not exist because I am using a local datasource.</p>
  
  <p>Am I missing an option to set the kendo grid to not read the remote datasource and just use local datasource?</p>
  
  <p>FYI the grid does not throw error and working just fine if the datasource is remote.</p>
