I do something very similar top this,
When you chroot it you should stay logged into chroot until you do an
exit of [control]D in the chroot.
After which your script will then logout, so you should remove the
logout command as it is not needed.
After removal your script should mount the virtual filesystem, chroot (
exit chroot manually) then unmount the virtual file system.
