On change client scripts are not working

On change client scripts are not working.

Created a new client script with simple alert/addinfomessage. This new on change client script written on Assigned to field is also not giving any message. 

What can be the reason of on change script not running?

@prit123  Script looks correct. 

How are you testing it ? Your script should work on form load as well as changing the assigned to field value.
