Gravity does not escape a black hole. There was gravity already
when there was no black hole. The gravity of the matter does not
disappear when that matter becomes a black hole.
 Nothing can come out of a black hole.
Not even a photon.
But a graviton, yes.
As graviton is neither an observed nor a theoretical particle it
is far from clear what it can do. Anyway, virtual particles used
in quantum field theories can travel faster than light and
backwards in time, which is sufficient for escaping a black hole.
