Reg pwiki front controller

We are displaying a chart in pwiki page. On click of chart we are bringing an overlay panel. Wanted to know if the piwik front controller would be invoked in case of overlay panel load event?
If ajax calls are being used on piwik application, how do we ensure that the control gets transferred to Piwik front controller


If you want to funnel requests through Piwik’s FrontController, it has to first go through index.php.
