I have been trying to use phaser examples in my games. I noticed that the examples are not using states. The game that I am developing is using states, so I can't use the examples because I keep getting errors. 
 
	Here's an example of what I am talking about:
 
	Phaser example:    
 
	game.input.onDown.addOnce(updateText, this);
 
	 
 
	my code
 
	game.input.onDown.addOnce(this.updateText(), this);
 
	 
 
	What am I doing wrong? What can I do different?
