// pass n template name parameters
// the last parameter contains the object that defines the template. 
// pass either an object literal or a function that returns an object for the last parameter
Templates.define('postSubmit', 'postEdit', {
  // assign either an object literal or return an object from a function
  helpers: { 
    post: function (id) {
      Posts.findOne(id);
    }
  },
  
  // assign either an object literal or return an object from a function
  events: function () {
    if (Session.get('someSetting')) {
      return {
        'submit form': function (e) {
          e.preventDefault();
          // do stuff
        }
      };
    }
    
    return {
      'submit form': function (e) {
          e.preventDefault();
          // do other stuff
