[Solved] Own Payment Module - Emails

[rickczsu]

Hi. I have my own payment module. Everything works correctly except emails.
I copied my module mails to mails folder and I am sending them over
$orderHistory->changeIdOrderState($this->new_state, $order);
$orderHistory->add();

Mail arrives but instead of 

Order date: 2.1.2012
i see
Order date: {date}

Any idea why this happens?
Thank you


EDIT

Easy solution. Just send params you want with Mail function
