Healthbar actor widget, access specific actor on shoot

Hey there,

hope you all doing fine and enjoying the weekend.
I have an problem to access the specific actor widget for the healthbar of the Ai-Actor.

The healthbar is working fine for each Ai. But only get refreshed if i shoot a character.
Each Ai Character has an health variable. This variable i check with the one actor widget with a line trace. Each Ai actor has the one actor widget.
But I will access each health variable from each Ai Charakter with the one actor widget. At the moment the actor widget only redraw with the specific Ai char. health variable.

What can I do?

UPDATE

@Everynone has the solution. Great work.

Here is the example video of the actor widget problem.

The hint from @Everynone works like a charm.
Thank you.
