Custom Home Button In ArcGIS API for Javascript

Question

Can you please take a look at This Demo and let me know how I can set up a custom home button

 var map;
 require(["esri/map", "esri/geometry/Point",
 "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol",
 "esri/graphic", "dojo/dom","dojo/on", "dojo/domReady!"], function (Map, Point,
 SimpleMarkerSymbol, SimpleLineSymbol,
 Graphic, dom, on) {
 map = new Map("map", {
 center: [0, 0],
 zoom: 5,
 basemap: "topo",
 slider: false, // set to false to remove default zoom buttons
 spatialReference: { wkid: 4326 }
 });
 on(dom.byId("zoomInBtn"), "click", function(evt){map.setZoom(map.getZoom()+1);});
 on(dom.byId("zoomOutBtn"), "click", function(evt){map.setZoom(map.getZoom()-1);});
 on(dom.byId("goHome"), "click", function(evt){});
 });

Your "goHome" function can just use the centerAndZoom function as described in the API documentation. So the code for your function procedure would be:

map.centerAndZoom([0,0],5);
