Hat Plugin Not Giving Me Hat

So... I am making a hats plugin as a gadget for my plugin, and when I open the inventory the hat doesn't come on and the inventory doesn't close... I have no idea what the problem is and I never get error messages .-. Help me please! I think it is a simple error.

• No need to uncancel the event (this might even break another event handler).
• Do not close the inventory in the click event, schedule a 0 tick delayed task (runTask, for example) in which you close it.
• Do not instantly open inventories when you just closed one. Once more, schedule a 0 tick delayed task opening one.
• After you close the inventory, I assume you want to return; instead of continuing execution.
• Check if the following are null/available (in the format "method call, check you need to perform")
  • getCurrentItem(), check if not null
  • getItemMeta(), hasItemMeta()
  • getDisplayName(), hasDisplayName()
• After setting items, it might sometimes be necessary to call updateInventory()
• Have you even debugged the code? For example, print out the current item's name, or the slot number
