Order by Title and Menu order not working

In our jQuery ajax method, we write a WP_Query like mentioned below.

$filter_args = array(
        'post_type' => 'Custom_post_type',
        'post_status'=>'publish',
        'posts_per_page'=> -1,
        'orderby'     => 'title menu_order',
    );

But the results are not shown correctly. The order still shows them in the way that we ordered each item(Drag&Drop) and not with the title. We require a result based on both the menu order and the title.?

The page I need help with: [log in to see the link]
