Summary
I want to make a Custom UI Widget based of ModelDialog. I set all UI’s Up just in case. There is a issue with the button responding instances. All the buttons are binded with the 100% accorat type of responded buttons for the Pop Up Dialog Devices.
Its all set but the buttons won’t work for no reason, i testet in live edit to binding the responding queue keys. I removed the Custom UI and all the buttons worked normally after I change it back to the Custom UI, sometimes 1/2 times worked to responding the Custom UI buttons.
I even tried with Click-Event same thing same resolve

Additional Notes
Note: Pop Up Dialog Device has not the correct linked binded for the Custom UI and this is a Major Bug. That confusing the new uefn developers and senior developers. I recommending to Patch the Bug to avoiding if Peoples doing the ViewBinding these Devices without using Verse.
