[1.6.4] Updating Textures on Items?!

[Mecblader]

Hello, I am making a mod and I have an item that places down 16 different blocks with the same block id, but a different metadata. I have the block placement down, you basically [shift-Right-Click] and it changes a nbt value and that determines the metadata of the block placed. My problem is that I want the item's texture to update to a different texture every time I [shift-Right-Click]. I have tried this before, but the texture does not seem to update. Does any one have any ideas an how I could update the texture, is there some sort of method that updates the texture or can you "tick an item like you can a block". I would appreciate any help anyone can give me. Thanks in advance!!!

I sorry, I meant to say that I want to update the item's texture. Does anyone know how to remove an item and add another item with a different meta data into a players inventory.
