im trying to learn how to make datapacks

{
  "type": "minecraft:crafting_shaped",
  "group": "Dirt",
  "category": "equipment",
  "pattern": [
    "@@@",
    "@&@",
    "@@@"
  ],
  "key": {
    "@": [
      "minecraft:gold_block"
    ],
    "&": [
      "minecraft:dirt"
    ]
  },
  "result": {
    "id": "minecraft:enchanted_golden_apple",
    "components": {
      "minecraft:item_model": "minecraft:dirt"
    },
    "count": 1
  }
}
why doesn't this work?
