In your drawing pin 3 on the DS-chip is not connected. This is not a wise thing to do, if this pin is left floating the DS can stop to work. Depending on current leakage in the chip and other varoius sources for charge a voltage can be built up on this pin if left floating and the safety functions for low battery voltage in the DS can be trigged. You do not want that.

Connect a suitable battery or ground the pin! You can find this information in the datasheet under the description of each pin. They put it there for a reason and they do not joke.....
