if button will make continuation bets the whole way thru without catching then this is an OK call if he plans on calling down without any futher scarecards, possibly wat he was intending to do. He cant do that anymore when the ace comes so instead of calling down which would now be the wrong play he is putting you to the test tryig to get u to fold a j or any other mediocre/drawing hand. his bet and folding are the only plays he really has here, folding is a the better play but seems like he was stuck to his PP and didnt want to fold
ps C/R i think for him is to risky with that board so the i see the donk bet a lot
