flop / turn decision

[car ramrod]

Absolute 2/4 5 handed

BB is not very good, donks a lot, calls alot.
Button is ok, he is loose pf but plays ok post flop. I have a note on him that he played his straight draw aggressively.

I open in the CO with A9o, cold called by button, BB calls.

flop: A5K two hearts

BB bets into me, I raise, Button 3 bets, we all call. (I wanted to cap so bad but I didn't, prolly should have)

turn: Q non heart

BB donks again, do you call or raise. Button is still to act. What hands do you put button on?

Anyone cap the flop?
