Not adding em tag in IE

Question

Here is my code.

<ul class="children">
<li class="page_item page-item-378 page_item_has_children"><a href="http://zealousys.com.au/service/mobile/ios/">iOS</a><em>+</em>
<ul class="children">
    <li class="page_item page-item-382"><a href="http://zealousys.com.au/service/mobile/ios/iphone/">iPhone</a></li>
    <li class="page_item page-item-384"><a href="http://zealousys.com.au/service/mobile/ios/ipad/">iPad</a></li>
</ul>   

And jQuery for him

$this.find("li").each(function() {
    if($(this).find("ul").size() != 0) {
           $(this).find("a:first").after("<em>"+ opts.closedSign +"</em>");
        }
}

It works in all browsers, but not in IE9 ... Here is the link for a working example here

In IE, this post, similar to Internet Explorer, restricted this form of a web page to running a script or ActiveX control.

When I allow blocked content, it works fine.

Use $(this)on the first line. A clear error in my console in Chrome, Firefox also
