Candy.Core.connect form change after disconnect

I'm using candy in my web server to connect in my public room from openfire server. I'm using Candy.Core.connect('jid') option to login. All works fine, but when I logout from room (pressed 'X' near room name) the connection form will be the defoult ones (User/Pass required). Why I get this issue and how can I fix it? 

EDIT: Even if I fail to put 'jid' password it changes the form to default
