Loading GameObject with the Script Attached from the AssetBundle.

Hi, what is the procedure i need to follow while loading a GameObject with the script attached from the asset bundle ? I created a AssetBundle by exporting AssetBundle using BuildPipeline, which contains a GameObject (Cube) with a script attached to it. I am trying load this GameObject from the AssetBundle by downloading it from WWW.LoadFromCacheOrDownload. When i try to load the GameObject i am getting warning Referenced behaviour script is missing. How can I load the GameObject with the script ? It would be really helpfull if someone who has tried this guide me on this. Thankyou.
