[jQuery] getJSON not finding any data

[expresso]

I have the following setup on my page inside a function:

    $.getJSON("http://localhost:59396/xxx/xxxHandler.ashx?
action=xxxjson",
        function(data) {
        alert('got here');
        $.each(data.items, function(i, item) {

        carousel.add(i, mycarousel_decodeEntities(item.ImageTag));
                if (i == 3) return false;
            });
        });

I know that if I take that url and render it in the browser straight
up, I get this:

[{"ImageTag":"\u003cimg src=\"http://www.xxx.com/
cat_image/1659D.jpg\" alt=\"\"\u003e"},
{"ImageTag":"\u003cimg src=\"http://www.xxx.com/
cat_image/536.jpg\" alt=\"\"\u003e"}]

where xxx is our domain.

So not sure why it's never getting to my alert inside function(data)
