How to use Jquery if any field is being changed using javascript?

I have hidden field whose value is being changed as per change of other field using javascript.

Now I want jquery event function which can track this change of hidden field and do the needful.

I tried with this :

jQuery("#bannersize").change(function()

but it didnt worked for me as i wanted.

How can i do it?

The following should trigger a "change" event. Call this code after you change your hidden field value:

$('#bannersize').trigger('change');
