Narrative:
We were initially cleared to climb to 3;000 ft and a right turn to heading 130. The first officer was hand-flying the aircraft. We were then cleared to climb to 6;000 ft and proceed direct to an enroute fix. Out of approximately 4;000 ft the first officer called; 'autopilot on'. At 6;000 ft we saw that the aircraft was not leveling and the first officer manually corrected. We reached 6;250 ft and then leveled at 6;000 ft. We were then cleared to 12;000 ft and proceeded normally. Departure did not make any comment. When the first officer called out 'autopilot on;' neither one of us confirmed that the pfd display changed from F/D to cmd. So the autopilot was not engaged.
