HelperForm toolbar button not shown

[Koko888]

Hello,

 

I'm trying to generate a sample form, but I can't get the 'save' button in the toolbar, here the code:

public function formCategories()
    {
        $fields_form = array(
            'form' => array(
                'legend' => array(
                    'title' => $this->l('some title'),
                ),
                'description' =>
                    '<ul>
                        <li>'.$this->l('some description.').'</li>
                    </ul>',  
                'submit' => array(
                    'title' => $this->l('Save'),
                ),
                'buttons' => array(
                    array(
                        'href' => 'http://someurl',
                        'title' => 'Generar',
                        'icon' => 'some-icon',
                    )
                ),                
            ),
        );
        
        $helper = new HelperForm();
        $helper->title = ;
        $helper->show_toolbar = true;
        return $helper->generateForm(array($fields_form));
    } 

This code only generates the button in the 'buttons' array  but not the 'save' button in 'submit' array. Any idea of what I'm doing wrong?

 

Thanks in advance
