Login Module changes via CLI not getting reflected without jboss restart

I am running few login module related commands through cli add() .

It is successfully added in standalone-full.xml. But this is not getting reflected without jboss restart.

I tried adding

{allow-resource-service-restart=true}

at the end of the command. But no luck.

I tried to reload using 'reload' command, but I am getting the following exception and the whole application goes down

I like to see the changes getting reflected without jboss restart.

Am I doing something wrong? Please give me some solution or alternatives.
