Change tracking for flat viewmodels, all properties must be observables

	var getObjProperties = function (obj) {
	var objProperties = [];
	var val = ko.utils.unwrapObservable(obj);

	if (val !== null && typeof val === 'object') {
	for (var i in val) {
	if (val.hasOwnProperty(i)) objProperties.push({ "name": i, "value": val[i] });
	}
	}

Using the simple change tracking

	var viewModel = {
	Name: ko.observable("Pete"),
	Age: ko.observable(29),
	Occupation: ko.observable("Developer")
	};

	applyChangeTracking(viewModel);

	viewModel.Occupation("Unemployed");

Modified track changes knockout extended that can handle detection of changes to complex objects

	var traverseObservables = function (obj, action) {
	ko.utils.arrayForEach(getObjProperties(obj), function (observable) {
	if (observable && observable.value && !observable.value.nodeType && ko.isObservable(observable.value)) {
	action(observable);
	}
	});
	};

	ko.extenders.trackChange = function (target, track) {
	if (track) {

Example of change tracking behavior after applying complex object detection

	var viewModel = {

	Skills: {
	Tdd: ko.observable(true),
	Knockout: ko.observable(true),
	ChangeTracking: ko.observable(false),
	},
	Occupation: ko.observable("Developer")
	};

Changes required to trackChange and getChangesFromModel methods to support change tracking as well as detection

	ko.extenders.trackChange = function (target, track) {
	if (track) {
	// ...
	// ...

	if (!target.getChanges) {
	target.getChanges = function (newObject) {
	var obj = target();
	if ((typeof obj == "object") && (obj !== null)) {
	if (target.hasValueChanged()) {

Highlighted portion of example illustrating how we deal with wholesale replacement of a complex object within an observable

	if ((typeof obj == "object") && (obj !== null)) {
	if (target.hasValueChanged()) {
	return ko.mapping.toJS(obj);
	}
	return getChangesFromModel(obj);
	}
