javascript - Subscribing with $geoWithin returns empty array -

everytime try return data collection returns empty array. i'm using iron router , code:

client:

meteor.call('insertevent', {     "eventloc": {         "type" : "point",         "coordinates": [              eventlongitude,              eventlatitude         ]} }  function getbox() { var bounds = googlemaps.maps.mapseek.instance.getbounds(); var ne = bounds.getnortheast(); var sw = bounds.getsouthwest();     session.set('box', [[sw.lat(),sw.lng()],[ne.lat(),ne.lng()]]); }  getbox(); 

server:

meteor.publish('publicplaces', function(box) { var find = {     eventloc: {         $geowithin: {             $box: box         }     } };  return events.find(find); }); 

routes:

router.route('/seek', function () {   this.render('seek');   meteor.subscribe('publicplaces', session.get('box')); }; 

i think, error in box value. according mongodb manual have specify longitude first, , code session.set('box', [[sw.lat(),sw.lng()],[ne.lat(),ne.lng()]]); seems conversely.
