It's hard to tell from that video, there are a few things that cause that rotation.
Rotating / Spinning in any scenario is cause by turning your head, moving the handle, or both. When you square up and flatten off at the wake to pop the trick, make sure you're not turning your head to look over your back shoulder when you flip. I'm betting this is your problem. Look straight over. You can practice this on a trampoline.
As you're flipping, if you pull the handle back toward your navel where it started while you were edging in, you should be able to straighten back out and land in the proper position. Don't forget to turn you head to look back over your front shoulder at the same time to look in the direction you're riding in.
You have an "out the back" rotation, instead of straight up and over flip. Usually this is caused by standing too heavy on the back foot. When you edge in, think about weighting the board evenly, and when you square up to pop, stomp down with your front foot to push off. This should level the board, and help you flip straight over, and will probably help fix your rotation problem as well.
Have you landed them one wake?
