Init.d code not quite working

The filtered out data from a MQTT live stream is dumped into a csv file named mqtt.csv and the dumping process is done by executor_start_up_job.txt which is written in BASH (has a shebang).

I want to make the dumping of the filter daemon, i.e. in the background, and also want to make it in so that every time the system is rebooted it is done automatically. So I've concluded to write an init.d script, and contents of my code is:

#!/bin/bash
set -x

requested_command=$1

start() {

        /home/ed/start_up_job/executor_start_up_job.txt &
}
# Restart the Dump
stop() {

        killproc executor_start_up_job.txt
        echo
}
### main logic ###
case $requested_command in
  start)
        start
        ;;
  stop)
        stop
        ;;
  status)
        last_line=`cat mqtt.csv | tail -1`
        echo "last print line: $last_line"
        ;;
  restart)
        stop
        start
        ;;
  *)
        echo "Usage: $0 {start|stop|restart|status}"
        exit 1
        ;;
esac
exit 0

Once I have inserted set -x I get the following output:

+ ./MySQL_table_update_daemon.sh start
+ requested_command=start
+ start
+ exit 0

Q: If I can make this code to work, then I will place it into the /etc/init.d/ directory, so that it can work every time. However currently it does not work and the output without the set -x the is nothing i.e it's as if I've just pushed enter in the terminal.
