Make sliders work

[basicNew]

It is not clear to me what should the sliders be publishing and to which channel. On the ROS side getting this:

[WARN] [WallTime: 1417983319.846068] Could not process inbound connection: [/rosbridge_websocket] is not a publisher of [/start/initial_marker]. Topics are [['/start/marker/feedback', 'visualization_msgs/InteractiveMarkerFeedback'], ['/rosout', 'rosgraph_msgs/Log'], ['/tf2_web_republisher/cancel', 'actionlib_msgs/GoalID'], ['/tf2_web_republisher/goal', 'tf2_web_republisher/TFSubscriptionActionGoal'], ['/goal/marker/feedback', 'visualization_msgs/InteractiveMarkerFeedback']]{'message_definition': 'string data\n\n', 'callerid': '/start_interactive_moveit', 'tcp_nodelay': '0', 'md5sum': '992ce8a1687cec8c8bd883ec73ca41d1', 'topic': '/start/initial_marker', 'type': 'std_msgs/String'}

So, sliders work before any sort of motion planning is achieved. After that they break.
