Pointer Enter & Pointer Exit work together?!

How is that possible?
Is there something wrong I am doing?
Here is a code of that functions:

public void onMoneyTriggerEnter()
{
moneyText.enabled = false;
print("Enter " + moneyText.enabled);
}
public void onMoneyTriggerExit()
{
moneyText.enabled = true;
print("Exit " + moneyText.enabled);
}
