change event not working for a textbox when the value is assigned externally

Question

I have a textbox and a button. When I click the button, it sets certain value in the textbox. I want to submit the page whenever the value of the textbox is changed.

You need to do this, when you are setting or changing the value of the text input chain it with .change() too:

 $("#click").click(function () {
    $('.set').val('Why am I not getting the alert saying  - Changed! ').change();
  }); //-------------------------------------this one here-------------^^^^^^^^^

So whenever you set the input value this way the change event will be triggered right after click.

May be this could help

$("input").on('change keyup', function () {
    alert("Changed!");
});
