Hi,

I have reproduced your situation by the given code and I saw that you are accessing the row id incorrectly.
To get the row id you can access it from ‘formatObject.row.id’. You are trying to access it from formatObject.row.data
formatObject.row.data contains the datafields with their values and $ object with id and index.

I suggest following the given example and accessing the row id —> formatObject.row.id

Here is an example of logging the row id in the console on checkbox click: stackblitz

I will wait for the result!
