Model not loading the texture

Hi, 
I have a 3d model and the texture, the model is properly loading in the game but the texture isn't but in block bench it does load perfectly 
here is the line in my json model file : (dragon.json)
"texture_size": [256, 256],
"textures": {
    "0": "flying_broom:dragon/dragon_domado",
    "particle": "dragon_domado"
},

and my folder architecture is : 
flying_broom
├── textures
 │            └── dragon
 │                   └── dragon_domado.png
└── models
    └── items
             └── models
                    └── dragon.json
cheers for the help
