Is there any possibility event bubble down

JavaScript

Go back to my example code, which I’ll post below. Some changes had to occur to get it working.
Can you find those changes?

$(document).on('click', '.one', function() {
  alert('click1');
});

$(document).on('click', '.two', function(e) {
  e.stopPropagation();
  alert('click2');
});
