ESP32-S3 with ILI 9341 cannot detect button

[atomino-max]

I am looking for a example where after drawing a button I can detect just is pressed.
I try after defined a button never button.contains is working.
I hope somebody can help me to go in the right way.
Thanks in advance.

Below my result, it's working , the button selection has no accuracy, but how
can manage the touchscreen with interrupt making free from the loop ?
