How can I play montage when I touch the button?

It works good with keyboard input but not working from Widget blueprint. Could anyone help me ? Also tried with event tick if I do that the other buttons with different anim montage mapped are not working. And I had Touch Interface also

Open Montages —> Select Default Slot in slot section.
Open Boxer Animation Blueprint —> Add Slot default slot node between State Machine and Out Pose.

Already added that one. Not working
