Copy a template and insert in db

Hi guys,

I've got a problem. I am trying to create an extension that copies a template from the module folder(s). (Like the standard tpl_editor), but also put information in the database, for easier sorting and filtering of templates. But it seems that when I call the function "copyTemplates" with "onsubmit_callback" it doesn't add the field to the database. Does anyone know how I can call a function with "onsubmit_callback" and call the standard function for adding the fields to the database.
My thanks.

My database table

Code:

---

--
-- Table `tl_tplsorter`
--

CREATE TABLE `tl_tplsorter` (
  `id` int(10) unsigned NOT NULL auto_increment,
  `tstamp` int(10) unsigned NOT NULL default '0',
  `templateName` varchar(60) NOT NULL default '',
  `templateFile` varchar(80) NOT NULL default '',
  `templateCategory` varchar(60) NOT NULL default '',
  `templateDescr` varchar(120) NOT NULL default '',
  PRIMARY KEY  (`id`),
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

copyTemplates function

Code:

---

public function copyTemplates()
        {
                // Copy an existing template
                if (file_exists(TL_ROOT . '/system/modules/' . $this->Input->post('templateFile')))
                {
                        $strOriginal = preg_replace('#.*/(.*)$#', '$1', $this->Input->post('templateFile'));

                        if (file_exists(TL_ROOT . '/templates/' . $strOriginal))
                        {
                                $_SESSION['TL_ERROR'][] = sprintf($GLOBALS['TL_LANG']['tl_tplsorter']['exists'], $strOriginal);
                                $this->reload();
                        }

                        $this->import('Files');

                        if ($this->Files->copy('system/modules/' . $this->Input->post('templateFile'), 'templates/' . $strOriginal))
                        {
                                $this->redirect($this->getReferer());
                        }

                        $this->reload();
                }
        }

my config array

Code:

---

'config' => array
        (
                'dataContainer'              => 'Table',
                'enableVersioning'            => true,
                'onsubmit_callback'                          => array(array('tl_tplsorter','copyTemplates'))
        ),
