Creating a feat for Pathfinder

[JazzIsBlues]

I want to create a feat for Pathfinder that comes originally from the "Book of Exalted Deeds" in D&D 3.5. The feat is called "Intuitive Attack" and basically allows a wisdom based character to use their wisdom modifier instead of their strength modifier for melee attacks. Much the same way that Weapon Finesse works. I've created the feat, but it isn't affecting the attack bonus on the character sheet.

Recommendations?

I'm a software developer so you won't frighten me with technical details I just need to know where to modify the feat so it does what I need it to do.

Thanks
