Clarification

At a high school game last night Team A was leading Team B by 3 points with about 20 seconds left. Team A stole the pass and the player went up for a dunk. He missed the dunk and hung on the rim for a few seconds. The ball bounced up, and eventually fell in while the player was still hanging on the rim. The official blew his whistle, and then all three officials discussed the call. They ended up counting the basket without any infraction, which put Team A up by 5 points with 9 seconds left. The place was going crazy. My only thought is that they said the player was protecting himself, but they should have disallowed the basket due to basket interference. Any other ideas of what may have been the ruling.
