Narrative:

Center gave air carrier airline flight a new altitude to climb to of 17000. Center also called traffic at our 10 O'clock position and said he was climbing to 16000 and gave us a frequency change. We called the traffic and changed frequencys. For unknown reasons, the captain did not initiate the climb. Although I said we were cleared to 17000 and dialed it into the altitude window, the captain did not climb until we received a TCASII alert.
