Passing a variable into a template for Google map

I’m new to Meteor, so this is a noob question: I have a Google Map inside one of my templates, and I’m wondering if I can pass a latitude and longitude from the Template helpers, for example:

  'someLat': function(){ 
    return -31.5;
  'someLng': function(){
    return 150.1;

<template name="googleMap">
  <div id="map"></div>
  <script type="text/javascript"> function initMap(){...
     //This is where I want to use {{someLat}} and {{someLng}} }

The problem is, I have Javascript inside my template that holds the map. I know this probably isn’t the correct way to implement this, but I’m wondering if there is a way to retrieve these values inside the template and use it in the JS in my template.
