How do I use AJS.toInit to make my Javascript save data from an AUI form?

[Sondra Menthers]

I created a form in AUI with a Save to file option in Javascript.  I wrapped AJS.toInit around my script but it doesn't save the form input data to the file.  Is there a plugin I can use or another example?  I just want the data entered in the form to be saved somewhere or go somewhere.  It can go to JSON, text, email, anything, I just want to save the data entered in the form.
