Answer 1

Fire the event manually after setting the value using the change() function.

$(document).ready(function () {
    $("input").change(function () {
        alert("Changed!");
    });
    $("#click").click(function () {
        $('.set').val('Why am I not getting the alert saying  - Changed! ');
        $('.set').change();  //Manual fire of event.
    });
});
