Touchscreen does not call handler.

Hi everybody!
I'm trying to use touchscreen with qt5 app.
The buttons pressed normally, I see the pressing action.
However, a handler don’t call.
If I connect a USB mouse, everything working fine.
How can I check and fix this problem?

So, I spent almost four days for this problem. But solved it today. Just need use pressed() slot instead clicked().
