Hi daviddam,
I believe the problem is not caused by the ajax request you make, but by the fact that you have moved the RadDockableObject. If this is the case - I prepared a simple project to demonstrate how you can get the desired behavior - please find it attached.
In case my assumption is not correct, please prepare and send us a simple running project, demonstrating the problem.
Best wishes,
