[jQuery] jQuery: noConflict

[Dennis Madsen]

I'm trying to use jQuery inside a CMS which use mootools - therefore I
use noConflict.
I have this sample code:

        jQuery.noConflict();

        (function($) {
                function doSomething() {
                        //some jQuery Stuff here..
                        alert("something");
                }
        })(jQuery)

        jQuery(document).ready(function() {
                doSomething();
        });

I would like to call the function doSomething() when my DOM is ready.
Why can't I? I also like to call the function as a JavaScript method
in my HTML.
