[1.12]Advancement function not running

[GiantNuker]

Hi, My current problem is that my function won't run - Advancement:

{
	"display" : {
		"icon" : {"item": "mocakes:cake_sponge"},
		"title": {
			"translate": "mocakes.advancements.sponge.title"
		},
		"description": {
			"translate": "mocakes.advancements.sponge.description"
		},
		"frame": "challenge"
	},
	"criteria": {
		"cake": {
			"trigger": "minecraft:inventory_changed",
			"conditions": {
                "items": [
                    {
                        "item": "mocakes:cake_sponge"
                    }
                ]
            }
		}
	},
	"parent": "mocakes:cake/next",
	"rewards": {
		"experience":100,
		"function": "mocakes:sponge"
	}
	
}

My function:

tell @p Here's A FREE Refund! :D
give @p sponge 1

Should execute function after player gets a sponge cake in thier inventory.

File Path: "WORKSPACE/src/main/resources/assets/mocakes/functions/sponge.mcfunction"

Achivement shows toast, and apperars, but the function wont run.

Have you tried running the function through the /function command? I have a feeling functions in the mod itself might not work, since they're per-world.
