Pushing too hard\too little with AJo?

Live tourny $20 + 5 w\ unlimited rebuys in the first hour and add-on. Field of 66 with payout to top 6.

Final Table, 8 handed. Mostly loose passive. Chip leader is solid, 2nd in chips is very laggy. Villain in the BB loose passive.

Hero 3rd in chips with 23k but far behind chipleaders at 45k and 42k. Rest of the table 15k or less. blinds at 2k\4k

folds around to Hero in MP. Hero raises to 12k. BB moves all in for his last 12k. Hero calls 2k more.

Anything wrong with that play on the bubble?
