A few things...
You need a more "squatty" approach to the wake. If you could lessen your approach to the wake by 3-5 feet, and still clear the wakes, that would be ideal. You want to come into the wake in a squatty body position, and spring striaght up at the top of the wake. You should be going for vertical pop.
OK, also before you attempt this trick, I would dial-in two things. I would dial in my handle-pass for the trick. Do this by slowing the boat down to 15-18MPH or so, and doing surface 360's riding straight behind the boat (just spin in place, without jumping). That is the best way to practice doing your handle-pass. Next, I would recommend that you do HS FS 180's. If you get used to doing 180's, then you will be used to rotating your body in the direction.
If you want to just say...screw it and go straight to trying the 360 again (instead of doing the things I recommend), then I would suggest a few things. First off, the squatty approach. Trying to get more vertical pop (which will make the handle pass easier). And finally on most (but not all of your spins) you took off from the wake with too much weight on your front foot.
