The variable PS1 is being used only in interactive shell, to access it you need to start your script with bash -i rename.sh.

Minimal example:

$ echo 'echo $PS1' > test

then compare

$ bash test
$ bash -i test

To run the script directly as an executable, add the following to the initial line

#!/bin/bash -i

Notice this works only if you chmod and run the script directly (e.g. ./rename.sh), and not with bash rename.sh, otherwise you'll have to call bash -i rename.sh again.

Edit

To change the terminal title directly, you can echo the control codes directly. Try

echo -e '\033]2;SomeTitle\007'

or, inside a script, with variables

title="SomeTitle"
echo -e '\033]2;'$title'\007'
