Adding profile fields

Hi there, I’m trying to add new profile fields to the bbpress profile screen. so far I’ve been able to add the profile items I want like so

add_action(‘bbp_user_edit_after_name’,'lp_add_profile_settings’);

question now is, how to I get the profile items to save properly. is there a bbpress hook or wordpress hook that I can use to get my user_meta settings to save?
