Captain reports he heard yelling from the ground crew and realized their emb-145 aircraft was rollin...

Narrative:

We pulled into the gate at ZZZ and set the emergency brake. I then turned off the 'fasten seat belt' sign and hydraulics. After that; I slid my seat back to pack up my things. A few seconds later I heard some yelling from the ground crew. At that point I realized that the plane was moving forward and reached for the emergency brake; but the emergency brake was already set. I then moved my seat forward and applied the foot brakes which then stopped the plane. The ground crew then had to push us back because the plane had moved too far forward of the gate. I then called maintenance to let them know the emergency brake was not working. The emergency brake was not working correctly.
