When you created the pen drive install did you give yourself space for persistence? Its an option to allocate additional space when creating the drive to allow room for additional applications and files. Using Ubuntu's USB startup creator this option is called Stored in reserve extra space If you used unetbootin it is referred to as space used to reserve file access across reboots.

If you did not choose to allow additional space then it will not save any changes after a reboot.
