jQuery events with dynamically loaded widgets not working

jQuery events with dynamically loaded widgets not working

Short question:
When I dynamically load a div on the page in jQuery, it seems to not respond to jQuery events.  Is there some way to register the events needed?

More detailed description:

I have a class called closebox that when clicked, closes the box and serializes the widgets.  This is working well for divs that were loaded when jQuery was initialize:

    $('.closebox').click(function (event) {
        event.preventDefault();
        var hpanel = $(this).closest('div.hpanel');
        hpanel.remove();
        serializeWidgets();
    });

The problem is that when I dynamically load a new div (widget) in jQuery, the closebox doesn't work.  I dynamically load this widget using the load function with some C#/MVC code:

var widget = $("<div>").load("@Url.Action("GetWidget","Widget")", { 'id': id },
                                               function (response, status, xhr) {
                                                   if (status == "error") {
                                                       alert("An error occurred while loading the results.");
                                                   }
                                               });
// widget is then appended to the DOM...

When that widget is dropped on the page, it does not respond to the close box being clicked.
