When I use my iPhone 4S's touch screen while charging, sometime it is not working correctly. For example; if I touch something in the middle screen, it acts like I touch some bottom in the border.
Is this normal behavior or should I go back to the Apple Store?

That's definitely not normal behaviour!

It could be something to do with earthing or voltage though as the screen is capacitive, so try charging from another source to see if it does the same thing. e.g. if you're charging from USB on your computer, try it on another computer if possible, or with the mains adapter. If that fixes your problem, it's possible you have a voltage issue or earth leakage issue on the port.

If it doesn't fix it, then the problem is likely with the iPhone itself.

I've had problems in the past where I was charging my iPhone on a work PC and sometimes when I touched the phone it would reset it. Luckily there was no damage caused, but it was a little weird.

    Then it sounds like you may have a faulty mains charger, or the socket you're plugging it into is badly earthed. You could have badly regulated power at your location, and the mains adapter doesn't do enough to smooth this, however a laptop or desktop computer will have a far heavier duty power supply to clean it up when it converts from AC to DC. – AlanJC Aug 10 '12 at 10:27
