The Teleop could work, but the robot could not pick up the instructions from it. The ControllerManager has a constructor that takes a tf2_ros::Buffer input, when this is used, no additional TransformListeners will be created. About teleop, this is the expected result. It looks like your simulator isn't subscribing to a command topic.
