Fetched data not updating automatically

Fetched data is not updating automatically, means Employee form have Emp ID and Employee Name, and there is another form having Employee ID field which is linked to employee ID and one field employee name, whenever i enter employee id in other form it automatically fetches employee name from employee master, but if i change employee name from employee master it will not reflect to the old entries on the other form.

It usually fetches on save, but you might like this:
