Having HomeButton and Overview together on ArcGIS Sever JavaScript API - arcgis-server

Question

Using ArcGIS Server JavaScript Api I am having issue on having Home Button and Map Overview on the map. For whatever reason the home button is not showing up the map. Here is the script:
<script>
require([
"esri/map",
"esri/dijit/OverviewMap", "dojo/parser","dijit/layout/BorderContainer", "dijit/layout/ContentPane",
"esri/dijit/HomeButton", "esri/layers/FeatureLayer", "dojo/dom-construct", "dojo/domReady!"
], function(
Map, OverviewMap,
parser, HomeButton, FeatureLayer
) {
parser.parse();
var map = new Map("mapDiv", {
basemap: "topo",
center: [-126.416, 55.781],
zoom: 6
});
//===================================================== Overview
var overviewMapDijit = new OverviewMap({
map: map,
visible: true
});
overviewMapDijit.startup();
//===================================================== Shapefile
//add a layer to the map
var featureLayer = new FeatureLayer("http://somewhere/1", {
mode: FeatureLayer.MODE_ONDEMAND,
});
map.addLayer(featureLayer);
//===================================================== Home Button
var home = new HomeButton({
map: map
}, "HomeButton");
home.startup();
});
</script>
and CSS for Home Button is:
#HomeButton { position: absolute; top: 120px; left: 50px; z-index: 2; }
Why is this happening?

Answer 1

From your what I can see is that your "esri/dijit/HomeButton" module is loaded at 6th position whereas while writing the function(Map, OverviewMap, parser, HomeButton, FeatureLayer) you have mentioned the HomeButton parameter at the 4th position.
If your put your module also at the 4th position
require([
"esri/map",
"esri/dijit/OverviewMap", "dojo/parser", "esri/dijit/HomeButton", "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "esri/layers/FeatureLayer", "dojo/dom-construct", "dojo/domReady!"
]
and likewise all the parameters of the function at the correct position, then everything should go well
