The Gulfstream was being worked by me as a departure climbing to 23000 feet. The Regional Jet was a departure; which was pointed out to the sector. When I noticed that the Regional Jet was climbing slowly; I stopped the Gulfstream at 21000 feet; but didn't change the data block. The sector called to determine if the Gulfstream was stopped below the point out. The other controller felt that separation was lost. I felt that at least 3 miles was maintained at all times and lateral separation was maintained until vertical separation was established. I should have taken the handoff back and amended the altitude in the data block to show the aircraft was stopped at 21000 feet.
ZNY ARTCC Controller reported allowing less than required separation between successive departures and failing to enter the correct altitude in the data tag.
