Try to change:

wp_enqueue_script( 'wc-add-extra-charges', $this->plugin_url() . '/assets/app.js', array('wc-checkout'), false, true );

With that:

add_action('wp_enqueue_scripts', 'whateveryouwant_enqueue_scripts');

And add this:

function whateveryouwant_enqueue_scripts() {
   wp_enqueue_script( 'wc-add-extra-charges', WP_PLUGIN_URL. . '/assets/app.js', array('wc-checkout'), false, true );
}

Or something similar :-)

Try :P
