Teaching magic spells through weapons

I stumbled across this thread after searching the forums. I have been wondering how to do this for some time now. I am by no means experienced at hex editing, but followed some of the tutorials that xjcsx has, as well inserted the code in the same place he has illustrated in this video:

I can get it so that the characters will learn things from weapons, but there is no shown ability points gained after a battle. Any thoughts as to why this might be? Any suggestions would be appreciated. If I can get it to work correctly, I hope to make a patch for it that others can use without having to go through the hassle of figuring it out. Of course no credit of my own as I have just put into practice what others have already taught.

thanks
