item model won't work

i have everything in the spot they need to be,
texture is in namespace -> textures -> item -> crowntext.png
model is in namespace -> models -> item -> crownc.json
item definition is in namesapce -> items -> crown.json
Crownc refers crowntext as the texture, no mistake possible here since it was exported from blockbench.
And crown definition is as follows:
{     "model": {     "type": "minecraft:model",     "model": "crowdenn:item/crownc"     } }
and ive run the command ingame correctly 
/give @s minecraft:iron_helmet[minecraft:item_model="namespace:crown"]
but it still appears as a purple and black cube
