The bond is electrostatic between two differently charged ions

In practice the amine group NH#2# has a free electron doublet that picks up a proton from acidic environment and is converted to ammonium group (NH#3#+).The carboxyl group COOH looses a proton in basic environment and is converted to carboxylate ion (COO-).
