Javascript with callback

I have a simple piece of example code, in which I am passing a function (for call back) into a class.
When this function is called back, I wish to have a parameter passed back but this is not working.

Thanks for you help

<!DOCTYPE html>

<script language='javascript' type='text/javascript'>

function init() {
    var y;
    var myClassObj = new MyClass(5, calledBack); 

function calledBack(x) {
    alert("Got called back with "+x);

function MyClass(val, f)
    var data = val;
    function someFunc(x) 
       alert("someFunc "+x);


<div style="" >
