Issue with Widget Component (Button)

Hi ! I have added a widget component(with a button inside) inside an actor in the scene, i cast on the widget BP and promote the widget and his button to variables, in this way i can use the “on click” event on the button, the problem is that when i click on the button nothing appen(I have a widget interaction setted correctly, i can hovered and clicking the button in the scene), i’m doing something wrong ? PS: Sorry for my english.
