Call template using VB Raw in CMS widget?

[Scalemotorcars]

I've looked and I can't seem to find the answer to this one.

How do I call a custom template into a CMS widget?

I've tried creating a plugin and reRegister using vbcms_widget_cmsfcs_page but no luck.

$templater = vB_Template::create('my_template');
$templatevalues['my_template'] = $templater->render();
vB_Template:reRegister('vbcms_widget_static_page ', $templatevalues);

Then calling the template in the configure of the widget.

{vb:raw my_template}
