Using teb_local_planner with via_points and obstacle avoidance

I'm using ROS Kinetic on a real 2-wheel differential drive bot. I would like to use move_base with Global Planner and TebLocalPlanner to navigate through a set of waypoints. For `teb_local_planner`, I am publishing a set of points as nav_msgs/Path on the topic `/via_points`. I have the default parameters of teb_local_planner set up with changes to include via_points, such as `weight_viapoints = 5` and `weight_obstacle = 50`. My goal is to use this combination of Global Planner and TEBLocalPlanner to navigate through a preferred set of viapoints, while being able to avoid obstacles. The problem I am facing is that it seems like the viapoints do not seem to affect the global planner at all, even when I apply higher values such as `weight_viapoints = 50`. As explained in the [tutorial](http://wiki.ros.org/teb_local_planner/Tutorials/Following%20the%20Global%20Plan%20%28Via-Points%29), I do not want to set that too high as I still require some obstacle avoidance behaviour. I'm able to echo the `/via_points` topic and see the points are being published once. What am I missing? Is there any other approach to achieving waypoint navigation *with* obstacle avoidance? Any help will be appreciated!
