How does black hole gravity remain?

I think I read that when a stellar object collapses the gravity remains....that is, the gravity is not hypothesized to emerge from beyond the event horizon after the collapse of matter....almost everything else about the object "disappears" beyond the event horizon...so what's the mechanism that makes gravity remain outside the event horizon? Why does it remain but apparently nothing else?? (I think we also can detect spin and charge...so maybe my question applies to them as well...)

The mechanism that "makes gravity remain outside the event horizon" is the same one that makes the earth orbiting around the sun - the curvature of space-time...

Yes, gravity is the effect of the curvature of space-time. It is not susceptible to the black hole's pull, it is the black hole's pull.
