onbeforeunload meteor

gistfile1.js

Names = new Meteor.Collection("names");
Name = {
    remove : function(name, room) {
        return Names.remove({
            name : name,
            room : room,
            host : PARENT // It's a string
        });
    },
    get : function(name, room) {
        return Names.findOne({
            name : name,
            room : room,
            host : PARENT
        });
    },
    set : function(name, room) {
        return Names.insert({
            name : name,
            room : room,
            host : PARENT
        });
    }
};

// This does not work :(
window.onbeforeunload = function(){
    var test = Name.remove(Session.get('name'), Session.get('room'));
    return test.toString();
};

// But this alerts! How ?!
window.onbeforeunload = function(){
    var test = Name.get(Session.get('name'), Session.get('room'));
    return test.toString();
};

Name.get is a purely client-side call, which looks in our local cache. No methods!

Name.remove has to make server-side changes, so it does methods.
