Hi Atul,
With your current approach you can use css to hide the control bar instead of disabling it. This way it will be hidden on the page but your default button behavior will still work.
To get started with styling here is a link to the documentation to get setup with Koala.

In the past there was a widget called the datagrid extension that did this, but that is no longer maintained.
