How can I process SP.JsGrid select row event in sharepoint webpart?

I have sharepoint visual webpart with SP.JsGrid.

<SharePoint:JSGrid ID="JsGridControl" runat="server" JSControllerClassName="WritebackGridManager" JSControllerInstanceName="WGM" Height="200px" />

How can I process SP.JsGrid select row event in sharepoint webpart?

It's like jsGridControl.AttachEvent(SP.JsGrid.EventType.OnCellEditCompleted, OnCellEditCompleted) in WritebackGridManager.js
