Definitely raise more on the turn.
You have (almost) the nuts, and a draw to to the third nuts.
Lots of cards can kill action or put you behind (T, small clubs, any clubs, 9, etc..) Get the money in while it's good.
Button obviously likes his hand (raising you on flop) enough to call a good size raise on the turn. I make it to around ~3. Also commits the short stacks when they're almost assuredly behind.
