[Plugin: Jetpack by WordPress.com] Tracking contract submissions

I am using Jetpack to make contact forms. I like to track submission in Analytic/Adwords.

I read you can insert an Ajax event that will do the tracking (http://contactform7.com/tracking-form-submissions-with-google-analytics/ ).

My questions is:

1) Can I do that with Jackpack?
2) Where should I insert the code?

Thanks
