problem in using "Bend Curve" deformer

Hello
I am trying to use “Bend Curve” deformer in Gizmo in order to change foot position (photo1) to “point” (photo2).
Since the axis of rotation is the ankle, I am locating the Gizmo center on the ankle (photo3), activate “Bend Curve” deformer, and expect to receive “Bend Curve” control points (orange dots) on the ankle. Unfortunately the control points appear beside the ankle and I don’t know how to move them in order to be able to rotate the ankle to the desired position.
Any idea how to do it?
Thanks a lot
