.click() fails after dom change

Question

I searched on web but I didn\'t find any answer since this \"problem\" is not the usual one about the difference between .on() and .click(). With jquery 2.1.3 the click func

Answer 1

$('#button1').click(function() {
    $('div').html("
Hello
");
});

$('#button2').click(function() {
    alert(0); //THIS DOESN'T WORK
});

$(document).on("click", "#button2", function() {
    alert(0); //THIS WORKS!
});

This is correct code
