In your bost::bind call, the second argument should be the instance of
TrajectoryPlanner that the reconfigureCB method should be called on. I
think that something like this will work (or at least will lead you to
the next error):

f = boost::bind(&TrajectoryPlanner::reconfigureCB,
my_trajectory_planner, _1, _2);
