identify this vine please Answered

can anyone tell the name of this vine? i'm in jamaica and anyone else who has doesn't know the name of it either (i've seen it mostly in the hilly,cooler towns) i tried to get a pic of the old and new flowers together but it's kinda blurry ( very windy out) the new ones are red then they turn pink right before they fall off the vine i have taken the off the stakes it was on as it gets real heavy the older it grows but the vine doesnt get thicker just more leafy. all the birds like it especially hummingbirds .the scent from the flower is similar to night flowering jasmine though not as strong flowers are always open it maintains itself i have never watered it or pruned it... and i can't think of anything else ... thanks for the help
