I\'ve an element with two handler bound to it:
$(\'.pippo\').on(\'click\', function () {
One easier alternative with jQuery is to define a namespace for your click events:
$('.pippo').on('click.first', ...);
$('.pluto').on('click.second', ...);
// Remove only the pippo listener
$('.pippo').off('click.first');
Note that your classes pippo and pluto refer to the same element so using one or the other will not change anything.
