Events in multiplayer

I have an event in gamestate set to replicate, and a few variables also set to replicate (in gamestate).
I do some world delta time process (game loop) in my game mode and, on a signal I call a function in gamestate that updates the replicated variables , once the variables are updated I call the event in game state to notify a HUD sitting in player controller. The HUB begin play is bound to the event and this works premo, however when the event fires the HUD custom event doesn’t do anything.
