title: kendo grid How to get a row by field value
body: <p>I need to get a row(s) from my kendo grid, using a string as parameter to filter rows.
  the grid model is:</p>
  
  <pre><code>{
      id: "id_tipo_pagamento",
      fields: {
          id_tipo_pagamento: { type: "number", editable: false },
          desc_tipo_pagamento: { type: "string"}
  }
  </code></pre>
  
  <p>i tried this, but isn't working:</p>
  
  <pre><code> var grid = $("#kendoGrid").data("kendoGrid");
   var row = grid.tbody.find("tr[desc_tipo_pagamento=test]");
  </code></pre>
