I'm confused just reading some of these answers - yet I'm aware that they are all saying pretty much the same thing.
Get out there with your instructor, and during the preflight brief ask him about the ATTITUDES required. He should be able to draw you a picture of the ideal scene for entering and maintaining the turn. When he demonstrates the first one, watch carefully the picture outside, and listen (and feel when following through) for the changes of control surfaces and the sound of the RPM increase).
In an ideal world, with constant bank held (again with the help of maintaining the right ATTITUDE), the elevator position should not have to change - it should remain in a constant position and back pressure. However in reality, you will have to adjust to changes, and fix the errors. Have a think before you fly about how to compensate for inaccuracies.
Note also, in the left hand seat, the attitudes for a Left and Right turn will be markedly different. You will be sitting lower in a left turn, and higher in a right turn....
As for all aspects of flying, attitudes is the key. And Practise. Good luck.
PS. You say that the bank angle keeps slipping off. Get some sort of workcycle incorporated into your thinking. I suggest something like "ATTITUDE - LOOKOUT - PERFORMANCE".
ATTITUDE - Is it right? If not, fix it.
LOOKOUT - Yep, do it, and look well into the turn
PERFORMANCE - Glance at an instrument, and think about it whilst you return to Step 1: Attitude (now adjust as required). And so on....
