That is the way is is supposed to work. Your MBP does not supply enough power to charge the battery efficiently. It may be charging, but at a trickle rate and it will show as not charging. That is why a power adapter is included with the iPad. Use it.
Read more about charging the battery here.
Try using another cable or another usb slot.. it also may be that the power supply has weak power.
