Reference to a particular Prefab clone - unity3d

Question

I am developing a simple 2D game. In game, I've created a prefab for charcaters. and I am changing sprite of prefab runtime. This all execute fine. Now I want to apply click event on a particular prefab clone and want to increase scale of prefab. I am attaching a c# script what I have did till now.
public class ShoppingManager : MonoBehaviour {
public static ShoppingManager instance;
[System.Serializable]
public class Shopping
{
public string CharacterName;
public Sprite CharacterSprite;
}
public GameObject CharacterPrefab;
public Transform CharacterSpacer;
public List<Shopping> ShoppingList;
private CharacterScript NewCharacterScript;
/*********************************************Awake()******************************************/
void Awake()
{
MakeSingleton ();
}
/******************************Create object of the script**********************************/
void MakeSingleton()
{
instance = this;
DontDestroyOnLoad (gameObject);
}
// Use this for initialization
void Start () {
LoadCharacters ();
}
void LoadCharacters()
{
foreach (var characters in ShoppingList) {
GameObject NewCharacter = Instantiate (CharacterPrefab) as GameObject;
NewCharacterScript = NewCharacter.GetComponent<CharacterScript> ();
NewCharacterScript.CharacterName = characters.CharacterName;
NewCharacterScript.Charcater.GetComponent<Image> ().sprite = characters.CharacterSprite;
NewCharacterScript.GetComponent<Button> ().onClick.AddListener (() => CharacterClicked (NewCharacterScript.CharacterName, NewCharacterScript.Charcater));
NewCharacter.transform.SetParent (CharacterSpacer, false);
}
}
void CharacterClicked(string CharacterName, GameObject Char)
{
StartCoroutine (IncreaseScale (Char));
}
IEnumerator IncreaseScale(GameObject TempCharacter)
{
int i = 5;
while (i > 0) {
yield return new WaitForSeconds (0.1f);
Vector3 TempVector = TempCharacter.GetComponent<RectTransform> ().localScale;
TempVector.x = TempVector.x + 0.2f;
TempVector.y = TempVector.y + 0.2f;
TempCharacter.GetComponent<RectTransform> ().localScale = TempVector;
i--;
}
}
}
This code triggers click event and also it increases scale but of last clone, not of clicked prefab clone. What I am missing, I can't understand. What should I correct in this. and Yeah! I am also attaching code of a script that I've added on prefab.
public class CharacterScript : MonoBehaviour {
public string CharacterName;
public GameObject Charcater;
}

create collider for your object attach the script below to it this way each object is responsible for handling its own functionalities like increasing its own size
public class characterFunctionalities: MonoBehaviour{
void OnMouseDown()
{
StartCoroutine (IncreaseScale (this.gameobject));
}
IEnumerator IncreaseScale(GameObject TempCharacter)
{
int i = 5;
while (i > 0) {
yield return new WaitForSeconds (0.1f);
Vector3 TempVector = TempCharacter.GetComponent<RectTransform> ().localScale;
TempVector.x = TempVector.x + 0.2f;
TempVector.y = TempVector.y + 0.2f;
TempCharacter.GetComponent<RectTransform> ().localScale = TempVector;
i--;
}
}
}
