[otrs] Change Format Date in Customer Company Form

Hello, I customize AdminCustomerCompanyForm.dtl to get some dates. I had 2 new columns 'date' on the mysql database. I would like to change date format to french like dd:mm:yyyy when I 'add' or 'modify' a company. For the moment, I see date like this yyy:mm:dd hh:mm:ss I've already changed this file Kernel/language/fr.pm and I see in templates the short date dd:mm:yyyy But not in Add Customer Company / Edit (Change) Is this possible, and how can i do ?
