Busy Indicator is not working with OData Model

Hi All,

I am trying to make OData read call to get the data and I want to display a busy indicator until I get the data from backend.

To do this , I have used attachRequestSent and completed method and inside those I have used .show() and .hide() method. But these methods and never getting executed,

This is the order I have used:

1.                var oModelData;
2.             var oDataModelSearch = new sap.ui.model.odata.ODataModel("..<service     name>..",false);
3.             sap.ui.getCore().setModel(oDataModelSearch, "OModelSearch");
4.             sap.ui.getCore().getModel("OModelSearch").attachRequestSent(function(){
5.              sap.ui.core.BusyIndicator.show(10);
6.        });
7.             oDataModelSearch.read("/Entity",null,null,false,
8.             function fnSuccess(oData){
9.                 this.data= oData.results;
10.                 oModelData= oData.results;
11.             },
12.             function fnError(response){ });
13.             sap.ui.getCore().getModel("OModelSearch").attachRequestCompleted(function(){
14.                 sap.ui.core.BusyIndicator.hide();
15.             });
16.             return oModelData;

Is there somthing I am missing, or the order should  be something else.

PS: When I run this in debug mode, after going to line 4 its directly jumping to Line 7 skipping line 5.

Thanks in Advance!
