Load a Bootstrap popover content with AJAX. Is this possible?

Works ok for me:

$('a.popup-ajax').popover({
    "html": true,
    "content": function(){
        var div_id =  "tmp-id-" + $.now();
        return details_in_popup($(this).attr('href'), div_id);
    }
});

function details_in_popup(link, div_id){
    $.ajax({
        url: link,
        success: function(response){
            $('#'+div_id).html(response);
        }
    });
    return '<div id="'+ div_id +'">Loading...</div>';
}
