How to return a value with Meteor.call on client

Meteor.methods({
 test: function() { if (this.isSimulation) { 
return 1; 
// Client wants this to be 1 
} else {
 return 2; // Server wants this to be 2 
} } });
 Template.hello.events({
 'click button': function () {
 // Call the test method sync 
var clientResult = Meteor.apply('test', [], {returnStubValue: true});
 Session.set('result', clientResult); } });
