custom recipes not working

  "criteria": {
      "crafted": {
          "trigger": "minecraft:recipe_unlocked",
          "conditions": {
              "recipe": "namespace:unbreaking_totem"
          }
      }
  },
  "requirements": [
      [
          "crafted"
      ]
  ],
  "rewards": {
      "function": "namespace:crafted/oncraft"
  }
}```

here, once you craft the recipe the oncraft function should run but it doesnt. why?
the version is 1.20.1
