jQuery/Ajax log only first page

I’m using this WordPress theme: Flora – Responsive WordPress Theme for Creative Multi-Purpose

It use a lot of jQuery/Ajax feature for navigation between the web site pages.
I’ve this problem: when users visit my site I see on Piwik only the first page that they load. All the other pages are not logged by Piwik. I think that the problem is related on how my theme load the page, but I’m not so expert in jQuery/Ajax to understand why.

I’ve tested using the javascript code in the header and using the WP-Piwik plugin on both mode (javascript and PHP API).

Do you have any suggestion on how to solve?
