sap.m. SearchField Implementation not working

Hi Guyz,

I am trying to implement the SearchField in a table. My controller code is not working and i am not sure what mistake i am making. Please help.

View.xml

<Bar>

  <contentLeft>

  <SearchField id="search" search="onSuggest"

  width="100%"></SearchField>

  </contentLeft>

  </Bar>

controller.js

onSuggest: function(oEvent)

{

   var tpmla = oEvent.getParameter("newValue");   

       var filters = new Array();

       var oFilter = new sap.ui.model.Filter("MyJSONData>/CData",sap.ui.model.FilterOperator.Contains, tpmla);

       filters.push(oFilter);

      //get list created in view

      this.oList =sap.ui.getCore().byId("CData>/key");

      this.oList.getBinding("oItem").filter(filters);

}
