Renderer on object disabled after level reload

Hi

I'm sorry for a noob question, but I'm fighting with it for some time already. I've got a simple code on one object:

 // Use this for initialization
     void Start()
     {
         gameObject.SetActive(true);
         gameObject.renderer.enabled=true;
     }
     
     void Awake()
     {
         renderer.enabled=true;
         gameObject.SetActive(true);
     }
     
     // Update is called once per frame
     void Update () 
     {
         if (Input.GetMouseButtonDown(0))
     {
             ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             if(Physics.Raycast(ray,out hit))
             {
                 if  (collider.name == "start")
                 {
                     starting = true;
                 }
             }
         }
         else if (Input.GetMouseButtonUp(0))
         {
             starting = false;
         }
         
         if (discount.animEnd)
             //gameObject.SetActive (false);
             renderer.enabled=false;
             //Destroy (gameObject);
     }

After level reload using "Application.LoadLevel(Application.loadedLevelName);", the object is not visible. Also in Inspector the renderer on the object is disabled.

Thanks in advance
