If you hear a click then it would appear that the solenoid is engaging the starter teeth onto the flywheel. Maybe the internal contacts in the starter motor or dirty/worn. Could also be a dud battery or a dirty connection on that battery cable.
Just incase you didn't know (if you did then ignore), the small cylinder bit on the top of the starter motor is a solenoid. It's job is 2 fold. Firstly, when it receives power from the ignition switch (when turned to the start position), the energised solenoid pushes the starter motor shaft forwards to engage the starter teeth with the flywheel. The second job is that it closes some internal contacts that takes power from the big fat battery cable you connected to turn over the starter motor. When you release the ignition key, the solenoid returns to its steady state position and the contacts are closed thus stopping the starter from turning.
