Forever and pm2 exit when you logoff instead of running as daemon

I'm trying to get a node.js application to run as a daemon in the background. I installed pm2 with the -g option and I can start and have it run in the background. As soon as I disconnect with 'exit' the process stops. I have done the same thing on my raspberry pi and it keeps running. As you can see from the sequence below like the pm2 daemon exits when I disconnect.

Here is the command sequence:

root@edison-toll:~# cd pingerjs

root@edison-toll:~/pingerjs# pm2 start main.js --name "pingerjs"

[PM2] Process main.js launched
