Saving class fields in the Asset

Hello. I'm trying to keep my class in Unity 3D using Unity serialization. Asset creation is successful, but the fields of the class are stored empty. AssetDatabase.SaveAssets () not help me, class fields are left blank inside stored Asset.

To save, I use this code: http://pastebin.ru/IPfWk7TX

In this picture you can see that the Text Localize list has 3 elements, but they are not stored in asset.
