ItemCommand event is not being firing

Question

Hi all,
I am working on the asp.net custom control in which I am using repeater control to show radio buttons. I need to fire repeaters ItemCommand event when RadioButton is click. The problem I faced is RadioButton is not capabel of firing ItemCommend event and it does not have CommendArgument, and CommandName properties.
To accomplish I created asp.net server control, drived i from RadioButton and add CommendArgument, and CommandName properties in it. I also added a Button in it so that I can call the click event of this button programatically to fire repeaters ItemCommand event.
Now the problem I am facing is I have fired Button's click event but still ItemCommand event is not firing.
Any idea how to gat this thind done?
