Linux – How to run start up scripts on Amazon linux

I'm trying to create some script that should run on start.

Now I've created some myScript file under the /etc/init.d/
and then run sudo chkconfig --add myScript;

chkconfig --list myScript output is:
myScript 0:off 1:off 2:on 3:on 4:on 5:on 6:off

myScript:

#!/bin/sh
# chkconfig: 2345 98 02
# description:
# processname:

# Source function library.
if [ -f /etc/init.d/functions ] ; then
  . /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ] ; then
  . /etc/rc.d/init.d/functions
else
  exit 0
fi
KIND="_"

start() {
   echo starting `date` >> ~/myScript.log
}

stop() {
   echo stopping myScript
}

restart() {
   echo restarting
}

case "$1" in
  start)
          start
        ;;
  stop)
          stop
        ;;
  restart)
          restart
        ;;
  *)
        echo $"Usage: $0 {start|stop|restart}"
        exit 1
esac
exit $?

Now I can successfully run service myScript start and log record will be appended.
But if I run sudo reboot or restart the instance with AWS UI console it doesn't work as was expected.

Although runlevel output is:
N 3

Need some help.
