Google Maps within a dynamically loaded jquery Accordion

Question

I'm trying to load a google map within a jquery ui accordion with contents loaded by ajax.

 $("h2", "#accordion").click(function(e) {
  var contentDiv = $(this).next("div");
  if (contentDiv.children().length == 1)
  {
   contentDiv.load($(this).find("a").attr("href"));
   contentDiv.ready(function(){
    var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
     zoom: 8,
     center: latlng,
     mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
   })
  }
 });

That's my current code (Google Maps API V3), but it redirects to the url of the href when I click currently, obviously with no google map because there's no javascript in this response. If I comment out the map line everything works fine (except the map itself).
