Google Maps StreetView displays only the first time

I have a google map page populated with markers from database. In the marker InfoWindow is a clickable link that opens a jquery dialog with StreetView of the location. The problem is, that StreetView shows only the first time I click on the InfoWindow link. If I close the dialog and try to open it again (clicking on other infowindows or even the same one again) , I get my dialog with StreetView controls , the new address is shown too (with "Address is approximate") , but the rest of dialog is an uniform light grey color.

I've tried some warkarounds posted on stackoverflow (like this one) but the grey dialog persists in my case.

Marker creation with onclick listener:

function addMarker(feature) {
    var marker = new google.maps.Marker({
        position: feature.position,
        icon: icons[feature.type].icon,
        map: map
    });
    //Create Infowindow
    var infowindow = new google.maps.InfoWindow();
    var content = '<h1 id="Heading" class="Heading">' + feature.shopName + '</h1>' +
                  '<div id="iwcontent" class="iwcontent">'+
                  '<p><b>Naslov : </b>' + feature.shopAddress + '</br>' +
                  '<p><b>Telefon : </b>' + feature.shopTel + '</br>' +
                  '</div>'+
                  '<div id="iwsw" class="iwsw">StreetView</div>'
                  ;
    //Call StreetView
    google.maps.event.addDomListener(infowindow, 'domready', function () {
        $('.iwsw').click(function () {
            showStreetView(feature.position);
        });
    });
    .
    .
    .

showStreetView function:

//Display dialog with streetview
function showStreetView(position){
    var panoramaOptions = {position: position, pov: {heading: 34,pitch: 10}};
    var panorama = new  google.maps.StreetViewPanorama(document.getElementById("dialog-sw-canvas"), panoramaOptions);
    map.setStreetView(panorama);
    $( "#dialog-sw-canvas" ).dialog("open");
}

Dialog definition:

$(function(){
    $('#dialog-sw-canvas').dialog({
        title: 'Street View',
        width: 1024,
        height: 768,
        closed: true,
        cache: false,
        modal: true,
        onClose: function(){
            $('#dialog-sw-canvas').empty();
        }
    });
});

Everything works like a charm, but only once.
