Damage item after crafting

[Kuuu]

Hello. I'm trying to make it so my tool will get back in inventory with little damage after crafting.

I have this code:

 

 

@Override
        public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemstack)
        {
        	return true;
        }
       
        @Override
        public ItemStack getContainerItem(ItemStack itemStack)
        {
            ItemStack cStack = itemStack.copy();
           cStack.setItemDamage(cStack.getItemDamage() + 1);
            cStack.stackSize = 1;
            return cStack;
        }

 

 

 

But i don't get the item back after crafting, and i can't understand why. Please help.

Thanks, it works now, here's the code if someone needs it:

@Override
        public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemstack)
        {
        	return true;
        }
        
        @Override
        public boolean isDamageable()
        {
        	return true;
        }
        
        @Override
        public boolean hasContainerItem(ItemStack itemstack)
        {
        	return true;
        }
       
        @Override
        public ItemStack getContainerItem(ItemStack itemStack)
        {
            ItemStack cStack = itemStack.copy();
           cStack.setItemDamage(cStack.getItemDamage() + 1);
            cStack.stackSize = 1;
            return cStack;
        }
