Reading JQMEdit value

Hi,
when I press the "Login" button in the attached form the value of the "Password" edit control is blank although I compiled it.
If I press the "Login" button a second time after the message I shown the "Password" edit control contains the text I inserted.
Why the first time I can't retrieve the value of the "Password" edit control ?
Thank you,
Davide
