You’re missing posts from the first argument in both the add_filter() and add_action(). It should follow the format of

So add_filter('manage_edit-document_columns', 'my_columns'); should be

add_filter('manage_edit-document_posts_columns', 'my_columns');

And add_action('manage_document_custom_column', 'my_custom_columns'); will read:

add_action('manage_document_posts_custom_column', 'my_custom_columns');
