adhesive under metal on glass

Ok not sure if this will make sense. I bought a glass display case. Where the metal door handle goes (that seals it with a magnet on the glass case itself so it shuts) underneath that was a foam kind of sticker so the metal casing is not exactly on the glass. Its soft and I am not positive what material it is. I realized that I placed the handles in the wrong spot (functioning correctly, but I'd still like to have it correct).

Anyways I tried peeling off the sticker which is no problem but it breaks apart so I cannot restick it to reposition. Does anyone know where I can get more of these stickers so I can reposition the handle. They were bought from Ikea here is a link : http://www.ikea.com/us/en/catalog/products/10119206

Thanks!
