[jQuery] Embedded JavaScript Not Loading With .load() Call

[Steven]

I'm using this code for my website to load pages dynamically:

        var hash = window.location.hash.substr(1);
        var href = $('#nav li a').each(function(){
                var href = $(this).attr('href');
                if(hash==href.substr(0,href.length-4)){
                        var toLoad = hash+'.php #content';
                        $('#content').load(toLoad)
                }
        });

        $('#nav li a').click(function(){

                var toLoad = $(this).attr('href')+' #content';
                $('#content').hide('fast',loadContent);
                $('#load').remove();
                $('#wrapper').append('<span id="load">LOADING...</span>');
                $('#load').fadeIn('normal');
                window.location.hash = 
$(this).attr('href').substr(0,$(this).attr
('href').length-4);
                function loadContent() {
                        $('#content').load(toLoad,'',showNewContent())
                }
                function showNewContent() {
                        $('#content').show('normal',hideLoader());
                }
                function hideLoader() {
                        $('#load').fadeOut('normal');
                }
                return false;

        });

It works great. However, I'm using a script for tooltips as well -
when I load a page that has links/abbr's that need tooltips, the
JavaScript doesn't run on them. My solution to this was to add a
<script> in the #content of each page that needed tooltips, except
that doesn't work either.

Can anyone explain this to me? This is a bit frustrating; I may go
back to static pages.
