onRelease doesn't work

I know there are other threads on this but I can’t make any sense of them. I am pulling thumbnails in from an xml and looping through the xml to create empty movie clips then loading the thumbnail. I want to make the thumbnails clickable using the onRelease but cant get it to work.

Here is my code:

=================

var xPosition:Number = 16;
var yPosition:Number = 298;
var xText:Number = 7;
var yText:Number = 360;
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
thumb = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
video* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
thumb* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
movieTitle* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;

        if (i == 5) {                
            xPosition = 16;
            yPosition = yPosition + 105;
            xText = 9;
            yText = yText + 105;
        }
        _root.createEmptyMovieClip("myClip" + i, getNextHighestDepth());
        _root["myClip"+i].loadMovie(thumb*);
        _root["myClip"+i]._x = xPosition;
        _root["myClip"+i]._y = yPosition;
        _root["myText"+i]._x = xText;
        _root["myText"+i]._y = yText;
        _root.createTextField("myText"+i, getNextHighestDepth(), xText, yText, 105, 37); 
        
        myformat = new TextFormat();
        myformat.color = 0x000000;
        myformat.size =10;
        myformat.align="center";                
        myformat.font = "Arial";
        _root["myText"+i].text = '"' + movieTitle* + '"

’ + ‘TV Commercial’;
_root[“myText”+i].setTextFormat(myformat);

        xPosition = xPosition + 95;
        xText = xPosition - 9;            
        
        _root["myClip"+(i)].onRelease = function(){
            trace('onRelease running');
        }
    }                
} else {
    content = "file not loaded!";        
}

}

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load(assetPath);
