Plugin problem

[vsforums]

Hi,

Im writing plugin and i try to create hook in footer template but I have big problem which I cant solve.

Code in plugin:
$temp = vB_Template::create('example_template');
$temp->register('example_form_id', 'search_form');
$temp->register('gtsearch_q', $gtsearch_q);
$template_hook['footer_my_hook'] = $temp->render();

In footer template:
{vb:raw template_hook.footer_my_hook} and I get nothing!!! I checked and I have that template in $temp variable.

When I do in plugin:
$template_hook['footer_my_hook'] ="test";
Then I get in template "test" but when I want to send template it doesnt work!

What is interesting that it doesn't work only in footer template...

Any ideas ?
