Execute script from remote

Hello,

I want to assign two keys in my remote to execute two scripts. One is for power on and the other is for power off:

# cat on.sh 
#!/bin/bash

echo "on 0" | cec-client -s -d 1
systemctl restart kodi

# cat off.sh 
#!/bin/bash

kodi-send --action="PlayerControl(Stop)"   
systemctl stop kodi
echo "standby 0" | cec-client -s -d 1

I map thoose scripts in the remote.xml

# cat .kodi/userdata/keymaps/remote.xml | grep "on.sh\|off.sh"
      <start>System.Exec("/storage/on.sh")</start>
      <power>System.Exec("/storage/off.sh")</power>

The only one that work for me is the power off, I suspect that it is beacuse in the power on, the kodi application is not running.

Is it possible to execute a script when kodi process is stoped?

I will appreciate you comments.

Kind regards.
