Many kids won't tell. The reasons vary - too busy playing, not wanting to walk away from the TV or game, too embarassed.
Instead of getting him to tell you, start rewarding him for getting there on his own with dry pants. Keep watching him for his "I've got to go but am fighting it" signs and tell him to go try. Don't wait for him to tell you. Don't ask if he has to go. Simply tell him it's time to try. If he goes without you telling him, reward him. Remember two things: "I forgot" and "I was too busy" type accidents are common into early grade school AND your goal is to eventually not have him need your help at all. Watch him closely so he doesn't get too busy to go and encourage his independence.
