On ready patterns in Meteor

gistfile1.js

var eventsHandle = Meteor.subscribe('events');

var onReady = Deps.autorun(function () {
	eventsHandle.ready();
});

onReady.onInvalidate(function() {
	Events.find().observeChanges({
		_suppress_initial: true,
		added: function(id, event) {
			console.log(event);
			event._id = id;
			allPoints.addData(event);
		},
		changed: function(id, event) {
			console.log("Event changed:" + id);
		},
		removed: function(id, event) {
			console.log("Event removed:" + id);
			allPoints.clearLayers();
			buildMap();

		}
	});
});
