"When player finishes using item" trigger not working

Hello I am a modding beginner and i have some problems. 

I maked Plaster item and I set that it can be used(using animation:bow,using time 20 ticks). I want to set that when player finishes using it, he will get the regeneration buff but it only works with "When player stopes using item" trigger and you can get the regeneration only from clicking, not from waiting 20 ticks. It do not work with "When player finishes using item" trigger and I don't know why.

Can somebody help me with this?

Sorry from all my mistakes in writing but I am not an English speaker.
