Functions not responsive to attacker entity enchant field

I am trying to make a custom wolf armor enchantment that increases damage, which that part works fine. I've got the wolf dealing extra damage. But what does not working is the calling of the function:

How to recreate: Create a custom enchantment that has wolf armor as the item enchanted, then tell it to run a function as a post-attack: (Might also not work outside of just wolf armor.)

I've also tested and my function with the exact name space works in game I was able to run it using /function I have attached the datapack, ignore the .DSStore files, they are harmless.

Here's my code:
