How to track conversions in HBook with Google Analytics?

How can I track conversions? I would wish to use Google Analytics to track conversions, where should I insert my script?

You can use HBook global function "hbook_reservation_done" to insert your Google Analytics tracking code. It will be triggered each time a reservation is done.

Please check here  in the documentation for more detailed information. Your Analytics code is to be added instead of my_js_function() in the given example.
