I like your logic as to the button and maximizing value from him and not scaring his King away. However, you are allowing MP in so cheap on the flop and then on the turn that it makes this play difficult to like. You really need to be putting pressure on MP early on, pricing him out.

So, the first question is what is button raising with here on the flop?: Button's raise to 24 means he is strong - he could have bottom set, he could have K8 (not uncommon for this level). Most likely he has KJ or KQ and is over playing it OR Ah9h and is making the right play and needs to be priced out too!

So to the hand: There is 53 in the pot when it gets to you. MP has 61 left. You know you are getting MP's money in now, so the last thing you want to do is play this passively and give MP great odds. Also, did you ever think about what will happen if a heart shows up on the turn? Button is going to stop betting, perhaps (he did on the river, right?), and at the same time, you are going to be committed to MP's made hand. So you need to price MP out while hoping to keep the button in. How do you do that?

Say to reraise to 80 here. Button is going to call a lot, so you get his money in there and you are well ahead. Now there is 190 in the pot and 56 more for button to call. Well, if button is weak, you may very well see his money go in there with KQ. If he has a set, boom, you're gold. K8? Ship it, holla! If he has a terribly misplayed flush draw, you are good too. But let's say button folds - well, you just built yourself a $190 pot giving yourself excellent odds to win against isolated short stack. that's what you want.
