Fiori getContext Detail page SAPUI5

Hello all

I am currently workign on Fiori like App using SAPUI5. I have successfully built the Master page, and on item click I set the context and navigate to Detail page.

The context path from Master page is something like "/SUPPLIER("NAME")". The function in App.controller.js is as follows:

handleListItemPress : function (evt) {
var context = evt.getSource().getBindingContext();
this.nav.to("Detail", context);}

But I would like to know how can I access this context in the deatil page. I need this because I need to use $expand to build the url and bind the items to a table.

Here is my Detail.view.js

sap.ui.jsview("sap.ui.demo.myFiori.view.Detail", {
getControllerName: function () {
return "sap.ui.demo.myFiori.view.Detail";
},

createContent: function (oController) {
var page2 = new sap.m.Page({
     title:"Supplier",
     class:"sapUiFioriObjectPage",
     showNavButton:true,
     navButtonPress: [oController.handleNavButtonPress,oController],
       content:[list]});

var list = new sap.m.List("list2");
var itemTemplate = new sap.m.ObjectListItem({
            title : "{NAME}",
            type: sap.m.ListType.Active,
            number : "{LIFNR}",
            numberUnit : "ID",
            attributes : new sap.m.ObjectAttribute("attr2",{text:"{CITY}"}),
            press: [oController.handleListItemPress, oController],});
var test = this.getBindingContext();

list.bindItems(test.getPath()+"/MASTERDATA",itemTemplate);

Any suggestions would be highly appreciated.

Thanks
