How to pass and call a function as an argument in Javascript?

Question

I'm looking to pass an anonymous function to another function, but it doesn't seem to be working as I'd like.

I've attached the code, I think it'd give you a better idea what I'd to do.

How do I successfully pass a function as an argument, and then invoke it?

<script language="javascript" type="text/javascript">
function do_work(success) {
    success;
}

do_work(function () {
    alert("hello")
});

</script>

You have to actually call the function:

function do_work(success) {
    success();
}
