Proper way to load a level and unload the previous one

Hi. I've go a few memory problem On my iPod4 after loading one or two level the device crash. This not happen on my iPad2. I think that my problem is about memory management.
Can someone tell me what's the proper way to unload a level and load a new one?

I load two level in one time because one is for my GUI. Here my load level behavior

if(!isObject(MainMenuButtonBehavior)){
	%template = new BehaviorTemplate(MainMenuButtonBehavior);

	%template.friendlyName = "Level Button";
	%template.behaviorType = "LevelManagement";
	%template.description  = "Loads a new level when clicked";

	%template.addBehaviorField(level, "The level to load on mouse down", string, "");
	%template.addBehaviorField(guiLevel, "The GUI level to load on mouse down", string, "");
	%template.addBehaviorField(loadIcon, "Want to call the loading icon?", bool, false);
}

function MainMenuButtonBehavior::onBehaviorAdd(%this){
	%this.owner.setUseMouseEvents(true);
}

function MainMenuButtonBehavior::onTouchDown(%this, %touchID, %worldPos){
	if(%this.loadIcon){
		startLoadIcon();
	}

	%guiLevel = "~/../data/levels/" @ %this.guiLevel @ ".t2d";  
    hudWindow.schedule(500, "loadLevel", %guiLevel);

	%level = "~/../data/levels/" @ %this.Level @ ".t2d";  
    sceneWindow2D.schedule(500, "loadLevel", %level);
    
    $currentLevelName = %this.Level;
    
    echo("Level Name: " @ $currentLevelName);
}

I think that with:
hudWindow.endLevel(); 
sceneWindow2D.endLevel();

Inside "function MainMenuButtonBehavior::onTouchDown(%this, %touchID, %worldPos)" the problem should be resolved but I'm not sure of it.

Do you think that this tutorial is still good?

@Andrea - Try putting more time between the schedules. Set the loadLevel for the HUD to about 600 or 700.

Here is my behavior code. Tried to do what you suggested to me but with no luck:

if(!isObject(MainMenuButtonBehavior)){
	%template = new BehaviorTemplate(MainMenuButtonBehavior);

	%template.friendlyName = "Level Button";
	%template.behaviorType = "LevelManagement";
	%template.description  = "Loads a new level when clicked";

	%template.addBehaviorField(level, "The level to load on mouse down", string, "");
	%template.addBehaviorField(guiLevel, "The level to load on mouse down", string, "");
	%template.addBehaviorField(loadIcon, "Want to call the loading icon?", bool, false);
}

function MainMenuButtonBehavior::onBehaviorAdd(%this){
	%this.owner.setUseMouseEvents(true);
}

function MainMenuButtonBehavior::onTouchDown(%this, %touchID, %worldPos){
	if(%this.loadIcon){
		startLoadIcon();
	}
	
	//--------------------------
	hudWindow.endLevel();   
	sceneWindow2D.endLevel();
	//--------------------------
	
	%guiLevel = "~/../data/levels/" @ %this.guiLevel @ ".t2d";  
    hudWindow.schedule(800, "loadLevel", %guiLevel); //500

	%level = "~/../data/levels/" @ %this.Level @ ".t2d";  
    sceneWindow2D.schedule(800, "loadLevel", %level); //500
    
    $currentLevelName = %this.Level;
    
    echo("Level Name: " @ $currentLevelName);
}
