leaflet.js on click of control checkboxes

To have leaflet.js control do anything by clicking the control input checkbox, I did this way, to bypass to the singular structure of DOM (may label tags, inside the checkbox):

$('.leaflet-control-layers-overlays > label').on('click', function () {
                $('.leaflet-control-layers-overlays > label').each(function(i) {
                     if ($(this).find('input:checkbox').is(':checked') ){
                         $('div#div_legenda' + i).fadeIn('slow');
                     }else{
                             $('div#div_legenda' + i).fadeOut('slow');
                     }
                });
                   
             });
