.clone() only clones DOM elements. In order to clone JavaScript objects try jQuery.extend. Something like this

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

Typescript transpiles to JavaScript. So, JavaScript way will work fine.

Demo:

// Transpiled version of TypeScript
"use strict";
    var Restaurant = (function () {
        function Restaurant(id, name) {
            this.id = id;
            this.name = name;
        }
        Restaurant.prototype.getId = function () {
            return this.id;
        };
        Restaurant.prototype.setId = function (_id) {
            this.id = _id;
        };
        Restaurant.prototype.getName = function () {
            return this.name;
        };
        Restaurant.prototype.setName = function (_name) {
            this.name = _name;
        };
        return Restaurant;
    }());

// Test Snippet
var r1 = new Restaurant(1, "A");
var r2 = jQuery.extend(true, {}, r1);

r2.setName("B");

console.log(r1.name);
console.log(r2.name);
