Problem with onRollover and loadClip

1

Can you not initiate events with jps and loaded clips?

I am trying just to do a basic roll over function and its not working


function loadItem(itemID) {
    newsTitle = _root.newsxml.firstChild.childNodes[itemID].childNodes[0].firstChild.nodeValue;
    newsDate = _root.newsxml.firstChild.childNodes[itemID].childNodes[1].firstChild.nodeValue;
    newsArticle = _root.newsxml.firstChild.childNodes[itemID].childNodes[2].firstChild.nodeValue;
    var imageLength = _root.newsxml.firstChild.childNodes[itemID].childNodes[3].childNodes.length;
    thumbDepth = 9999;
    for (i=0; i<imageLength; i++) {
        this.newsThumbHolder.createEmptyMovieClip("newsThumb"+i,thumbDepth++);
        newsThumbHolder["newsThumb"+i]._x = i*105;
        var theNewsThumb = _root.newsxml.firstChild.childNodes[itemID].childNodes[3].childNodes*.attributes.thumb;
        thumbMCL.loadClip(theNewsThumb,this.newsThumbHolder["newsThumb"+i]);
        newsThumbHolder["newsThumb"+i].onRollOver = function() {
            trace("pewp");
            this.brightnessTo(150,0.5,"easeOutExpo");
        };
        newsThumbHolder["newsThumb"+i].onRollOut = function() {
            this.brightnessTo(100,0.5,"easeOutExpo");
        };
    }
    newsItemTitle.newstxt.text = newsTitle;
    newsItemDate.newstxt.text = newsDate;
    article.newsArticle.text = newsArticle;
}
