woocommerce variable product price on dropdown - wordpress

Question

Hello I m trying to make available the prices for the variations on the dropdown, at some point I were able to achieve it when were only one variable, but now I have two variables for the product but the price on the dropdown is not updating.
Based on Variable product attribute: Customizing each displayed radio buttons text value answer code, here is the code I use to get on the first step, but I need help to update the price of variations up to the second variable selected.
add_filter( 'woocommerce_variation_option_name', 'display_price_in_variation_option_name' );
function display_price_in_variation_option_name( $term ) {
global $wpdb, $product;
if ( empty( $term ) ) return $term;
if ( empty( $product->id ) ) return $term;
$id = $product->get_id();
$result = $wpdb->get_col( "SELECT slug FROM {$wpdb->prefix}terms WHERE name = '$term'" );
$term_slug = ( !empty( $result ) ) ? $result[0] : $term;
$query = "SELECT postmeta.post_id AS product_id
FROM {$wpdb->prefix}postmeta AS postmeta
LEFT JOIN {$wpdb->prefix}posts AS products ON ( products.ID = postmeta.post_id )
WHERE postmeta.meta_key LIKE 'attribute_%'
AND postmeta.meta_key != 'attribute_pa_alto'
AND postmeta.meta_value = '$term_slug'
AND products.post_parent = $id";
$variation_id = $wpdb->get_col( $query );
$parent = wp_get_post_parent_id( $variation_id[0] );
if ( $parent > 0 ) {
$_product = new WC_Product_Variation( $variation_id[0] );
//EDITADO PARA MOSTRAR CUANDO NO HAY STOCK MUESTRA AGOTADO
if($_product->managing_stock() && $_product->get_stock_quantity() < 1){
return $term . ' - AGOTADO';
}else{
return $term . ' - (' . wp_kses( woocommerce_price( $_product->get_price() ), array() ) . ')';
}
}
return $term;
}
