on the server page (php) that receive the facebook notice, you have to put an extra check so

if( facebook_data_come ) { 

   // 1 - insert the new data inside your table

   // 2 - on a separate database table that you will call for example facebook_notification_check where you have an INT of 0 or 1 (default to 0), update it to 1 after the first step above.

   // 3 - on the ajax php page you will first check if  facebook_notification_check is equal to 1, if so you will continue with your code and reset the facebook_notification_check back to 0 otherwise you return an empty string...
