Three things:

First, your script does not have a proper shebang (missing !), use
#!/bin/sh

Second, check that the script you created is actually executable (chmod
+x ...).

Third, / might already be read-only at the time the script is run. You
need to explicitly remount / rw, i.e. something like

#!/bin/sh
mount -oremount,rw /
touch /test
mount -oremount,ro /
