Trying to respawn prefabs after destroying them with a reset button

Hello All, I am a scripting newbie and I'm running into some serious problems. What I am doing is that at the start of the scene/level a grid of 9 prefab(Cubes) Instantiates. Also on the screen I have a "Reset" GUI button that is supposed to destroy all the prefabs(Cubes) and then respawn them. There needs to be a slight time delay between the time the cubes are destroyed from clicking the reset button to when the cubes respawn, so it the user can visually see it. I can't use Application.Loadlevel on the Reset button either, as the parameters of this project forbid me from doing such. I tried calling the function used to spawn the cubes in the script for the reset button, either its not working or since there is no time delay I can't see it happening. The following is my code:

Cube Spawning Script:

 //the WoodCube Prefab assigned in the inspector
 public var thePrefab:GameObject;
 
 //the # of WoodCubes that will be spawned 
 public var numberOfCubes:int = 9;
 
 //the ARRAY of spawnpoints that our cube will be spawned at
 private var spawnPointList:GameObject[];
 
 //array of which spawn points are currently available for spawning at
 private var spawnIndexAvailableList:Array = [];
 
 //variable to hold the total number of spawn points, saves having to recalculate
 private var numberOfSpawnPoints:int;
 
 function Awake()
 {
     //retrieve GameObject tagged as "SpawnPoint" within the "CubeSpawnPoints" GameObject which the script is a component of
     spawnPointList = gameObject.FindGameObjectsWithTag("SpawnPoint");
     
     //retreive # of spawn points
     numberOfSpawnPoints = spawnPointList.length;
     
     //make sure number of cubes doesn't exceed number of spawn points
     if (numberOfCubes > numberOfSpawnPoints) numberOfCubes = numberOfSpawnPoints;
     
     //make all spawn points available by setting each index to true
     for (var i:int = 0; i < numberOfSpawnPoints; i++)
     {
         spawnIndexAvailableList[i] = true;
     }
     
     //spawn X amount of cubes according to numberOfCubes
     for (var j:int = 0; j < numberOfCubes; j++ )
     {
         SpawnCube();
     }
 }
 
 function SpawnCube()
     {
         //generate a random integer to use as the index to select a spawn point from the list
         var randomSpawnIndex:int = Random.Range(0, numberOfSpawnPoints);
 
         //while the selected spawn index is unavaiable regenerate another one
         while (!spawnIndexAvailableList[randomSpawnIndex])
         {
             randomSpawnIndex = Random.Range(0, numberOfSpawnPoints);
         }
 
         //retrieve the pos and rot of the cube's spawn point
         var spawnedCubePosition:Vector3 = spawnPointList[randomSpawnIndex].transform.position;
         var spawnedCubeRotation:Quaternion = spawnPointList[randomSpawnIndex].transform.rotation;
 
         //instantiate (create) the WoodCube prefab with the above position and rotation
         var spawnedCube:GameObject = Instantiate(thePrefab, spawnedCubePosition, spawnedCubeRotation);
 
         //set the spawned cube as a child of the "CubeSpawnPoints" gameObject that this a Component of
         //this is so we can use SendMessageUpward within scripts attached to the WoodCube prefab to call functions within this script
         spawnedCube.transform.parent = spawnPointList[randomSpawnIndex].transform;
 
         //set the name of the cube as its index
         spawnedCube.name = randomSpawnIndex.ToString();
 
         //make the spawn index unavailable to prevent another cube being spawned in this position
         spawnIndexAvailableList[randomSpawnIndex] = false;
     }
 

Here is the Reset button script: //Includes both Back and Reset GUI Buttons var spawnpoint:GameObject;

 function OnGUI()
     {
         //Back Button takes you back to Main Menu
         if (GUI.Button(Rect(50,50,200,100),"Back"))
             Application.LoadLevel("MainMenu");
         
             //Reset Button destroys cube grid and reloads    
         if (GUI.Button(Rect(1430,50,200,100),"Reset"))
             Destroy(spawnpoint);
             
         
         GUI.color = Color.green;
         GUI.Button(Rect(50,50,200,100),"Back");
         GUI.Button(Rect(1430,50,200,100),"Reset");
         
         
     }
     
     var CubeController : CubeController;
     
 function Update()
     {
     
         CubeController.Awake();
             
             
     }

Obviously I'm writing in JavaScript as I'm not well versed in C# just yet. I'm really new at coding and pick things up fairly quickly, but I'm having a hard time doing this. Any help would be greatly appreciated. Thank you Community!
