In order to turn off caching in IconItemRenderer you will need to subclass it and override createIconDisplay.  For example:
package
    import spark.components.IconItemRenderer;
    import spark.core.ContentCache;
    public class NoCacheIconItemRenderer extends IconItemRenderer
        * When the icon display is created turn off the caching of its
        * contentCache so it doesn't cache images.
        override protected function createIconDisplay():void
            super.createIconDisplay();
            var contentCache:ContentCache = iconDisplay.contentLoader as ContentCache;
            if (contentCache)
                contentCache.enableCaching = false;
