Callbacks in block doesn't refresh

Hi,
The callback is included in the block builder (cf screenshot).
If add a other product (in the good term) i dont see it in the selector

function nxt_get_accessories_list() {
    $posts = get_posts([
        "post_type"   => "product",
        "tax_query"   => [
            [
                "taxonomy"    => "product_cat",
                "field"       => "slug",
                "terms"       => "accessoires"
            ]
        ]
    ]);
    $posts = array_map(
        function($post) {
            return [
                $post->ID,
                $post->post_title
            ];
        },
        $posts
    );
    return array_column(
        $posts,
        1,
        0
    );
}
