-(BOOL)trackMouse:inRect:ofView:untilMouseUp: Is never invoked

Question

I have subclassed NSControl to get my custom control, have subclassed NSCell to get my custom cell, over overridden -(BOOL)trackMouse:inRect:ofView:untilMouseUp and necessary methods in custom cell, have overridden + (Class)cellClass in customControl to return my customCell,

Cell draws fine on control, set enable, set dissable works fine, but Mouse events not getting triggered. While debugging i noticed that -(BOOL)trackMouse:inRect:ofView:untilMouseUp: is never invoked. As per "Control and cell programming guide" -

"Controls manage the behavior of their cells. By inheritance from NSView, controls derive the ability for responding to user actions and rendering their on-screen representation. When users click on a control, it responds in part by sending trackMouse:inRect:ofView:untilMouseUp: to the cell that was clicked"

Kindly tell if i am missing something - i have googled a lot got nothing useful.
