Not able to capture value of dropdown inside AG-GRID in angular

In Angular I am not able to capture value of dropdown selected value inside AG-Grid .

I am able to capture all other values in the AG-Grid except dropdown value.
Dropdown is a separate component and it is added via cellRenderer property of columnDefs.

here is my code of parent as well as child componen
