Just be patient, the roots will start to form. I've done the same thing and they do eventually root, it just takes a while. After it gets roots starting to grow, put it in a small pot with potting soil and keep it moist and sort of shaded for about a week and then gradually expose it to more sun.Eventually it will have enough roots to plant.
Good luck, I hope it works out for you. Kopper King is a nice one, but having another one is even better.
