[jQuery] Using the Accordion with Ajax generated content

[Ruby]

I am having troubles getting ajax content to work in an accordion. It
shows everything fully listed. Not sure what might be wrong... Here is
my code:

                        $('#EventListings').accordion({
                           header: '.EventsInListHeader',
                           active: false,
                           alwaysOpen: false,
                           autoHeight: false
                        });

                        // This is for the Events section
                        $.ajax({
                                        type: "GET", url: 
"xml/ConventionEvents.xml", dataType: "xml",
                                        success: function(xml) {
                                                
$(xml).find('event').each(function(){
                                                        var EventName = 
$(this).find('name').text();
                                                        var EventLoc = 
$(this).find('location').text();
                                                        var EventDate = 
$(this).find('dates').text();
                                                        var EventLogo = 
$(this).find('logo').text();
                                                        var EventDesc = 
$(this).find('desc').text();
                                                        var EventRegLink = 
$(this).find('register').text();
                                                        var EventMoreLink = $
(this).find('LearnMore').text();
                                                        var EventVidLink = 
$(this).find('video').text();
                                                        var EventVendorLink = 
$(this).find('vendorApp').text();

                                                        $('<div 
class="EventsInListHeader">'+EventName+' '+EventLoc+',
'+EventDate+'</div><div class="EventsInList" style="background-
image:url(/'+EventLogo+');"><span>'+EventDesc+'</span><a href="/
events/'+EventRegLink+'" rel="shadowbox;width=776;height=600"
class="EventsInListButtons">Register</a><a href="/
events/'+EventMoreLink+'?<%=SessionParam%>"
class="EventsInListButtons">Learn More</
a>').appendTo('#EventListings');


                                                });
                                        }
                        });
