Answer 1

click can be attached only to exsiting elements, .second is being added after you tried to add it a callback, on support delegation events :

$('.first').click(function(){
    $('#load').html('<a href="#" class="second">Twice</a>');
});

$('#containerId').on('click', '.second', function(){
    $('#twice').html('<a href="#" class="third">Third</a>');
});
