onChangeContentControl cannot be triggered

Hello @GGbeng

I see that you have posted a comment in this thread regarding the same issue:

Help: How to use this function (onChangeContentControl)

The onChangeContentControl function is currently found in the plugin development documentation. However, there is no detailed instruction document in the documentation. I tried to use this function directly, just like the functions labeled in events, without any reaction. If you have used it successfully, I hope you can help me.

Please try avoiding creating multiple threads based on the same problem.
I will close this thread and reply to the original one.
