Widget on Click not working

Hi,

There is a strange issue with working on different versions of the ue4 when it comes to 3d widgets.

I have a full working 3d widget in 4.16.2 when onclicked event is triggered

however

Exactly same setup I have done in 4.16.3 and when I want to click the button, the button appears as if its clicked by when I click the button again, it does appear that it got clicked, although when i see the blueprint simulation where " Right Mouse Button" event ïs triggered, it does show that a click input of the right mouse button is received but the action which it suppose to do , in this case just Print hello, its not working.

Is there an issue between the two versions when working with widgets? can any body on this globe can help me. I have transferred my work from 16.2 to 16.3 and continuing and I don’t want to go back to 16.2.

SOS please help guys
