I am trying to run my script to send pose to my movebase from msgs. But it runs the code and waits without throwing any error. My tracker is leg running is running and providing me a Peopletracked msg of PeopleArray(Person[] people) Person (geometry_msgs/Pose pose uint32 id). Can't figure out the problem as there is no error.

 class move_base_goal:
   def __init__(self):
      self.goal_pose = PersonArray()

  self.new_person = Person()
  self.goal_pose.people.append(self.new_person)

  if not self.goal_pose.people:
         return move_base_goal()
  rospy.init_node('movebase_goal_py')
  rospy.Subscriber("people_tracked", PersonArray, self.callback )

  def callback(self,msg):
    self.goal_pose.people[0].pose.position.x = msg.people[0].pose.position.x
    self.goal_pose.people[0].pose.position.y = msg.people[0].pose.position.y


  def movebase_goal(msg):   

    move = actionlib.SimpleActionClient('move_base',MoveBaseAction)
    move.wait_for_server()


    goal = MoveBaseGoal()
    goal.target_pose.header.frame_id = "base_link"
    goal.target_pose.header.stamp = rospy.Time.now()
    goal.target_pose.pose.position.x = self.goal_pose.people[0].pose.x
    goal.target_pose.pose.position.y = self.goal_pose.people[0].pose.y
    goal.target_pose.pose.orientation.w = 1.0

    move.send_goal(goal)

if __name__ == '__main__':

    x = move_base_goal()
   rospy.spin()
