sapui5 event registration for multiple objects – failed?

My first post in this community! I’m happy to be here. Already learned a lot of stuff but I have a question which I couldn’t solve with the existing questions yet.

Simple task:
I have two smart tables: “SmartTablePanel2” and “SmartTablePanel4”

In my controller I attach the event “DataReceived” to both smart tables at the event “onInit”.

enter image description here

Normally I wanted to have one function but it was not working so I tried to have two functions: “onDataReceived” and “onDataReceived2”. But this is also not working 🙁

My functions are quit simple:

My problem: In both events are fired but in the functions I only receive “SmartTablePanel2” … I would expect one is “2” and the other would be “4” but it is in both cases “2”!

First call:

Second call:

Thank you so much in advance
