Including scripts in AssetBundles on iOS

Hi, my problem is easy. I want to load assetbundle (scene with dependencies) into my scene, but scripts are not included. How can I save .bytes data inside assetbundle? and how can I read it? I am working on iOS so I can not use Reflection because is not supported. Is there any way to save scripts with assetbundle?

Downloading from internet (from the same location where assetbundle is) .cs files and then downloading and loading .unity3d file doesn't work.

Any idea/code/solution/example? Thanks
