ReCaptcha not showing on Contact page

I've installed ReCaptcha on Joomla 1.5. It shows up and works fine with default joomla template, but it disappears when I set gk_postnote as default template. Is there a work around for this?

I've added the following on line 64 on components/com_contact/views/contact/tmpl/default_form.php

<?php
global $mainframe;
$mainframe->triggerEvent('onCaptchaDisplay');
?>

Thanks

Nevermind, I found a solution myself. For anyone else looking for a solution to this. I found that the template has an altered version of the contact form under the template folder /templates/*template_folder*/html/com_contact/contact/default_form.php edited that instead and it works ok now. line 64 add
<?php
global $mainframe;
$mainframe->triggerEvent('onCaptchaDisplay');
?>
