Update data in module.exports by function

I have this JS code, and my functions change variable ‘index’, but not in module.exports. How can i fix it?

var Observable = require("FuseJS/Observable");
	var Bundle = require("FuseJS/Bundle");
	var stages = Observable();
	stages = JSON.parse(Bundle.readSync("stages.json"));
	var index = stages.nTag;

	console.log(JSON.stringify(stages.Stage1[index]));

	function onVar1(context) {
		index = stages.Stage1[index].Var1.tag;

	}
	function onVar2(context) {
		index = stages.Stage1[index].Var2.tag;
	}
	module.exports = {
		stages: stages.Stage1[index],
		onVar1: onVar1,
		onVar2: onVar2
	};

I did not understand the philosophy of working with Observable :smiley:
This code working fine

	var Observable = require("FuseJS/Observable");
	var Bundle     = require("FuseJS/Bundle");
	//
	var stages = JSON.parse(Bundle.readSync("stages.json"));
	var index  = stages.nTag; 
	var st     = Observable(stages.Stage1[index]);  //new var for exports
	function onVar1(context) {
		index    = stages.Stage1[index].Var1.tag;
		st.value = stages.Stage1[index]; //change value in exports
	}
	function onVar2(context) {
		index    = stages.Stage1[index].Var2.tag;
		st.value = stages.Stage1[index]; //there too
	}
	module.exports = {
		nstages:    st,
		onVar1: onVar1,
		onVar2: onVar2
	};
