Adding a permament AnimationClip

I made an custom inspector gui to help me with my animations but when i add an animationClip to an object in edit mode it only stays in edit mode so if i hit play animation is deleted instantly .Is there a way to add an permament animation clip to objects prefab? Im using gui so it is not realtime.

I try to add my animations like below

 AnimationState clip;
 
 clip = animation[aniname];
 animation.AddClip(clip.clip,NewName);
 clip = animation[NewName];
