How do I get the event listener for a button on the custom column to work?

Problem:
I'm adding custom buttons with custom functions because I didn't find anything related to override the in built editor. I'm creating a button programmatically and then appending it to ZingGrid. It works, it really appends to the custom column. However, the event listener for the button is not working.

Solution:
Have you tried using the ZingGrid column renderer? This is a life-cycle hook that will help you with creating custom buttons. In this demo, the event listener for the email button is working perfectly. Use it for reference.
