You need the supercaps to be in parallel to the power supply, not in series. However, before fixing your circuit, mind a few things: If you simply connect your supercaps between 0 and 5V, most power supplies / batteries will have trouble starting your system, since a discharged capacitor is essentially a short circuit.
