Cannot Bind to Event Dispatcher

In UE version before 4.14, I have no problem in binding a custom event to an event dispatcher from another widget, which is constructed dynamically via Blueprint. But now, such thing is no longer feasible.

In the image below, as you can see I have created an event dispatcher for a custom widget ButtonComponent.

I tried to dynamically create this ButtonComponent in another custom widget, but there’s no option to bind to its event dispatcher.

This never happened in previous UE version. Is this a bug or did something changed in UE 4.14 about event binding?

Try checking the context sensitive box in the search dropdown.

Very sorry this is terribly my mistake. It cannot bind to an event inside a macro, as shown in the screen shot (not in event graph tab). It is still perfect in the event graph.
