GUI button play animation

Hello, I got a problem on using Button play animation. I can press the button and animation can be played. But It seems the animation cannot be repeated or play inverse if i click in the button again. Is the process can be done in animator? thank you

Here is my script:

using UnityEngine; using UnityEngine.UI; using System.Collections;

public class play_anim_on_ui_button : MonoBehaviour {

 public Button Text;
 public AudioClip sound;
 public Animator ani;
 public Canvas yourcanvas;



 void Start () 
 {
     Text = Text.GetComponent<Button> ();
     ani.enabled = false;
     yourcanvas.enabled = true;
 }


 public void Press() 

 {
     Text.enabled = true;
     AudioSource.PlayClipAtPoint(sound, transform.position);
     ani.enabled = true;
     Destroy(Text,1);
     yourcanvas.enabled = true;

 }

}
