Function is not working in Widgets

Hello everyone,

I am making a shortcode for my theme, but there is a problem.
When I am making this shortcode, there comes automatically a
tag after it. I solved this problem with this function:

remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );

function wpse_wpautop_nobr( $content ) {
    return wpautop( $content, false );
}
add_filter( 'the_content', 'wpse_wpautop_nobr' );
add_filter( 'the_excerpt', 'wpse_wpautop_nobr' );

But the problem is that this function does not work in Widgets, does anyone know how to make this function work in widgets?

Greets,

Joren
