My OnClick won't trigger

I have a door in my game. I have debuged it and neither the OnClick(), nor the OnMouseOver() will trigger. Here are the Object Details:

Here is my Script: using UnityEngine; using System.Collections; using System.Collections.Generic; using UnityStandardAssets.Characters.FirstPerson; using UnityEngine.UI;

 public class EndOfMapDoor : MonoBehaviour
 {
 
     public FirstPersonController spieler;
     public int TriggerID = 0;
 
     FuseBoxWater myTrigger;
 
     EndOfMap eom = new EndOfMap();
 
     public Text statusLabel;
 
     // Use this for initialization
     void Start()
     {
         List<FuseBoxWater> myTriggers = new List<FuseBoxWater>(GameObject.FindObjectsOfType<FuseBoxWater>());
         myTrigger = myTriggers.Find(t => t.FuseID == TriggerID);
 
         eom = GetComponent<EndOfMap>();
     }
 
     public string target
     {
         set
         {
             eom.NextLevel = value;
         }
     }
 
     void OnMouseDown()
     {
         activate();
     }
 
     void activate()
     {
         if (calculateDistance(gameObject.transform.position, spieler.transform.position) < 4)
             if (Physics.Raycast(gameObject.transform.position, spieler.transform.position))
             {
                 if (myTrigger.isTriggerd)
                 {
                     eom.ChangeLevel(this);
                 }
                 else
                 {
                     statusLabel.color = new Color(255, 0, 0, 255);
                     statusLabel.text = "The door has an electric lock";
                 }
             }
     }
 
     private float calculateDistance(Vector3 p1, Vector3 p2)
     {
         float xDiff = p2.x - p1.x;
         float yDiff = p2.y - p1.y;
 
         return Mathf.Sqrt(xDiff * xDiff + yDiff * yDiff);
     }
 }
