Bind nice name does not work

[mhd-marjeh]

Hi,
I need to bind nice name to angular expression instead of using static name like the following,
nice-name="{{ctrl.getTitle(emp)}}"
the nice name changed in the html code, but the initial value still displays in the error message "Name in emp1 is required".

Is there any way to change "emp1" in the error message when the user fill form name?
