I made a tile entity block, and it has textures when i place it down, but it doesnt when im holding the block. what am i doing wrong?

{
    "parent": "block/cube_all",
    "textures": {
        "all": "tm:blocks/inventory_block"
    }
}

 

{
    "parent": "tm:block/inventory_block",
    "display": {
        "thirdperson": {
            "rotation": [ 10, -45, 170 ],
            "translation": [ 0, 1.5, -2.75 ],
            "scale": [ 0.375, 0.375, 0.375 ]
        }
    }
}
