Adding class to dynamically appended elements with jQuery function in ie8

Have tried a few options with no luck. I am using jQuery 1.9.1

Here is my function's code:

(function ($) {
    $.fn.createGallery = function(options) {
        var theObject = $(this);
        var settings = $.extend({
            // These are the defaults.
            server: 'http://localhost/jQuery%20Gallery/images/galleries/',
            galleryName: 'Test',
            galleryWidth: 800,
            galleryImageMargin: 20,
            galleryImageColumns: 2,
            galleryTargetFolder: 'homepage_gallery',
            imageQuality: 100
        }, options);

        var galleryImageWidth = settings.galleryWidth / settings.galleryImageColumns;
        var imageUrl = settings.server+settings.galleryTargetFolder;

        var otherMargin = Math.round(settings.galleryImageMargin / 2);
        var finalImageWidth = Math.round(galleryImageWidth - settings.galleryImageMargin);
        var finalImageHeight = Math.round(galleryImageWidth / 1.4);
        var finalGalleryWidth = settings.galleryWidth - settings.galleryImageMargin;

        $(this).before('<style>'+$(this).selector+' li:nth-child('+settings.galleryImageColumns+'n+1) { margin-left: 0; } '+$(this).selector+' li:first-child { margin-left: 0; } '+$(this).selector+' { width: '+finalGalleryWidth+'px; margin: 0px; } '+$(this).selector+' li { display: inline-block; list-style: none; margin-left: '+settings.galleryImageMargin+'px; margin-bottom: '+otherMargin+'px; } </style>');

        $.ajax({
            url: imageUrl,
            success: function(data){
                var extension = '.jpg';
                $(data).find("a:contains("+extension+")").each(function(){
                    // will loop through 
                    var filename = $(this).attr("href");
                    $('<li></li>').html('<a href="'+imageUrl+'/'+filename+'" class="fancybox"><img src="thumbnail.php?src='+imageUrl+'/'+filename+'&q='+settings.imageQuality+'&h='+finalImageHeight+'&w='+finalImageWidth+'"/></a>').appendTo(theObject);
                });
            }
        });

    };
}(jQuery));

Which is called like this, and works perfectly: HTML: <ul id="images"></ul>

jQuery:

$('#images').createGallery({
    server: 'http://localhost/jQuery%20Gallery/images/galleries/',
    galleryName: 'Test',
    galleryWidth: 800,
    galleryImageMargin: 20,
    galleryImageColumns: 2,
    galleryTargetFolder: 'homepage_gallery',
    imageQuality: 100
});

Now, what i want to do is add a class to the new elements so that i can target them in ie8 to add a class to it. I have tried this:

$(document).on('DOMNodeInserted', function(e) {
    $(e.target).addClass('triggerMargin');
});

Which i have placed in the bottom of the function and it works fine in firefox and chrome etc, yet it is totally ignored in ie8. Any ideas?

This was fixed by doing the following theObject.children('li:nth-child(2n+1)').addClass('triggerMargin');

where theObject is equal to $(this) for the object being targeted to add a class to it's children
