MB Term Meta doesn't work

Hi there,

I'm trying to configure some meta values for custom taxonomies, but it doesn't work.

I bought the bundle, i installed the plugin, then MB Term Meta add-on.

Here is my code:

add_action( 'init', 'create_corpo_raices_taxonomies' );

function create_corpo_raices_taxonomies() {

   register_taxonomy(
        'clientes',
        'property',
        array(
            'label' => __( 'Clientes' ),
            'public' => true,
            'rewrite' => true,
            'hierarchical' => true,
            'show_ui'               => true,
            'update_count_callback' => '_update_post_term_count',
        )
    );
}

add_filter( 'rwmb_meta_boxes', 'corpo_raices_meta_boxes' );
function corpo_raices_meta_boxes( $meta_boxes ) {

	$prefix = 'corpo_raices_';

        $meta_boxes[] = array(
        'title'      => __( 'Datos del Cliente' ),
        'taxonomies' => 'clientes',
        'fields'     => array(
            array(
                'id'   => '{$prefix}nombre_cliente',
                'name' => __( 'Nombre', 'corporaices' ),
                'type' => 'text',
            ),
        ),
    );

    return $meta_boxes;
}

I have more simple metaboxes using the Tab Add-on and Column, but MB Term Meta is not working.

Could you please, help me with this?

PD: I'm running WP 4.5

Thanks,
