Could not understand delegate system.

I have a widget, that have child widget with delegate object. Delegate should be executed on click.
When I create child widget, I bind a parent object to delegate. Then I click to widget, but nothing happens.
Logs tell me that delegate still not connected.
In debug mode I could see thart created widget and clicked widget have same type, but different address, so it different objects.
How could it be?

Could you show your blueprints/C++ to give a better idea of what your setup looks like? It would be helpful in order for others to help you solve your problem.
