So I shouldn't have tried to milk it more on the flop to get more callers?

Whatever you do, you have to be consistent with your bets when you do and don't have actual hands. If you are potting lots of flops with air and making weaker bets with made hands, observant opponents will take notice and adjust their play accordingly.

With regards to this specfic board, I don't think a weaker flop bet would have helped much. Your pre-flop action helped narrow down the hand range preflop, such that most people here hold a bunch of high cards. Given the rainbow flop, the only opponents that you are getting action from are those that called with a small-middle runs hoping to snap off aces. (This is assuming that you aren't betting so weak as to give someone odds to hit their two-outers on you.)

Additionally, if your opponents have marked you with A-A-x-x ot K-K-x-x, you can get a lot of action from even bottom two here. Considering this, and the fact that MP1 bet the turn with his case chips, the turn call is a no brainer (as Tilt already mentioned).
