        $actions = new Actions();
        $actions->setActionType(Actions::SIGNER);
        $actions->setPrivateNotes($request->input('template_name',''));
        $actions->setRole(Actions::SIGNER);
        $actions->setSigningOrder(0);

        $templateObject->setTemplateName($request->input('template_name',''));
        $templateObject->setNotes($request->input('template_private_notes'));
        $templateObject->setSequentialSigning(false);
        $templateObject->setEmailReminders(true);
        $templateObject->setReminderPeriod(2);
