As of 1.21.4 you also need an additional file, called an item model definition, for items. It would look something like this for example:
assets/testmod/items/suspicious_substance.json

{
  "model": {
    "type": "model",
    "model": "testmod:item/suspicious_substance"
  }
}```

The wiki has more info on these files if you’re interested https://minecraft.wiki/w/Items_model_definition, they can do a lot of cool stuff
