mongodb - Template subscription fail with location -

i have meteor app using d'burles:google-maps' , 'mdg:geolocation'. have list of places in collection doing geospacial query find places close me, have run on server since mini-mongo not support yet.

i'm publishing , able send , forth parameters narrow search of places, since geolocation takes second user's location, can't subscribe right away, otherwise location null , query won't know do.

i think problem in subscribing,

meteor.subscribe('nearest', mylng, mylat, radius); 

here code:

template.map.oncreated(function() { //****if subscribe here, results (if use fixed location, geolocation won't have given me results yet)     googlemaps.load();     var self = this;     meteor.subscribe('nearest', mylng, mylat, );      googlemaps.ready('map', function(map) {     //****if subscribe here, collection count 0     //i need subscribe here since when geolocation provided       var marker;       console.log(mycollection.find().count());       }); }); 

this publish, run in server folder:

meteor.publish("nearest", function (lng, lat, dist) {     return mycollection.find( {loc: { $geowithin: { $centersphere: [ [ lng, lat ], dist/3963.2 ] } }} ) }); 

anyone know why second location not subscribing correctly, or know way subscription based on user's location reactively?

i've been searching , searching no luck, appreciated!
