Rewrite your question. It's not clear at all what you are asking. — dkamins

Are you saying that clicking the button activates some server-side logic, and you don't want the callback() method to execute until it's completed? — Syntactic

Unless I've wildly misunderstood the question, this code will make a request to the page that the link leads to, and when the server has returned the response, executes the function:

$(document).ready(function() {
  $("#btnDownload").click(function() {
    $.ajax({
      url: $(this).attr("href"),
      complete: function(xhr, status) {
        callback();
      }
    });
    return false;
  });
});

I may have wildly misunderstood the question...

Your question is not clear. But I will give you a example.

For example, you wan to load a page by clicking on a image then after the page load is complete you want to do something you can something like this

$('#buttonid').click(function() {
    //this is the callback function of click event
    //if you want some other callback functions then you need something like this
    $("#somediv").load("page.php", function() {
       //callback function code of .load event
       alert('page loaded');
       });
 });

What you are asking is to have a callback function inside the default callback function of click event and a bit impossible from my point of view.
