Zápis dat do databáze – Unknown column ‚_submit‘ in ‚field list‘

Zdravím,

někde mám chybu a nevím kde, respektive nerozumím kde. Snažím se ukládat formulář (ve kterém proběhne ajax – dependentselectbox) do databáze.

presenter (formulář):

protected function createComponentTimesheetForm()
{
        $form = new Form;
        $form->addHidden('Tsk_ID');
        $form->addSelect('Cmp_ID', 'Firma', $this->timesheetManager->getCompanies()->fetchPairs('Cmp_ID', 'CmpName1'))
            ->setPrompt('Vybrat firmu')->setRequired();
        $form->addSelect('Prj_ID', 'Projekt')
            ->setPrompt('Vybrat projekt');
        $form->addText('TskName', 'Obor zájmu')->setRequired();
        $form->addText('TskDescription1', 'Popis úkolu')->setRequired();
        $form->addText('TskDateStart', 'Datum zahájení')->setRequired();
        $form->addText('TskDateEnd', 'Datum ukončení')->setRequired();
        $form->addText('TskTaskmaster', 'Zadavatel')->setRequired();
        $form->addText('TskWorked', 'Odpracováno (hod.)')->setRequired()->addRule(Form::INTEGER, 'Zadejte číselnou hodnotu');
        $form->addSelect('TskUser', 'Provedl', $employees = array(
            "user1" => 'user1',
            "user2" => 'user2',
            "user3" => 'user3',
            "user4" => 'user4',
            "user5" => 'user5',
            "user6" => 'user6',
        ))->setPrompt('Vybrat zaměstnance')->setRequired();
        $form->addSubmit('submit', 'Uložit');
        $form->onSuccess[] = [$this, 'timesheetFormSucceeded'];
        return $form;
}

public function timesheetFormSucceeded($form)
{
        $values = $form->getHttpData();
        $this->timesheetManager->saveTask($values);
        $this->flashMessage('Záznam byl uložen.');
        $this->redirect(':Front:Timesheet:');
}

model (uložení dat do databáze z formuláře):

public function saveTask($timesheetFormValues)
{
    if (!$timesheetFormValues[self::TASK_COLUMN_ID]) {
    $this->database->table(self::TABLE_TASK)->insert($timesheetFormValues);
} else {
    $this->database->table(self::TABLE_TASK)->where(self::TASK_COLUMN_ID, $timesheetFormValues[self::TASK_COLUMN_ID])->update($timesheetFormValues);
}
}
