New UI Button On Click(), how to play animation?

I have a little problem playing animations after pressing given button using the new UI system.
I have my animation created that I want to play after pressing the key but I just cant get it working.
After creating animation, I got animator (component) on my desired object, I also added animation (component).

I tried using script too, with no success.

Errors I get:
-The AnimationClip 'slideout' used by the Animation component 'GameObject' must be marked as Legacy.

After changing to legacy(in debug mode from 2 to 1)
-Animation clip 'slideout' is not retargetable. Animation clips used within the Animator Controller need to have Muscle Definition set up in the Asset Importer Inspector

Any ideas?
