When sodium bicarbonate and vinegar mix, they react with each other and one of the things that is made is carbon dioxide gas. The reaction needs heat to make it happen, so it takes heat from its surroundings, leaving the bottle feeling cold. The gas couldn't escape because it was trapped by the balloon.
