Now is working

      $(document).on('click', '.add_question', function() {
        $("#questions").append("<div>How are you?<button class='add_answer'>Add answer</button></div>");

      });
       $(document).on('click', '.add_answer', function() {
          alert("working..");
      });

Answer 2

live is not available on newer versions of jQuery so if you want to delegate events use on

  $("#questions").on("click", ".add_answer", function(){
      alert("working..");
  });
