Unless i'm terribly forgetting alot of things, this is just a scene made up in the movie. They never actually ventured into mt. doom. After Isildur cut the ring from Sauron's hand he just claimed it as his own.
Elrond and Cirdan who stood by him counselled him to cast it into the fires of orodruin, this way sauron would be destroyed, but Isildur refused and claimed the ring as a weregild for his father and brother.
They COULD have forced him, but this would surely lead to total enstrangement between the races and after all they swore an Alliance
