WebPack按需动态加载bundle

Question

We are using webpack 1.14.0 to bundle our application. Currently we are looking for an approach where we need to load a bundle on demand dynamically.

Our requirement is to load readme.md and example.md files dynamically from bundle. I am trying using require.ensure , below is the sample that I am trying

//app.js entry point for webpack config
require("./login"); //sample login file just contains console log stmnt.

window.clickButton = function () {
    require.ensure(['./ensureTest'], function (require) {

       var a = require('./ensureTest');

    });

}
console.log("App Loaded"); 

//ensureTest.js   testing to load this module dynamically on demand
define([], function(){
    console.log("Loaded ensure runtime");
});

Below is my webpack config

module.exports = {
    entry: ["./app.js"],
    output: {
        filename: "bundle.js"
    },
    module:{
        loaders:[
            {
                test:/\.es6$/,
                exclude : "node_modules",
                loader:"babel-loader"
            }
        ]
    },
    resolve:{
        extensions :['', '.es6','.js']
    }
}

When I run WebPack command I am able to see bundle.js and 1.bundle.js file created. Problem is when I am clicking on a button, only for the first time click is see "Loaded ensure runtime" message which is showing from 1.bundle.js

Clicking again on the button I cannot see the message "Loaded ensure runtime"

My overall motive is to load the bundle and its contained module dynamically.

I'm pretty sure you can only load it once. Once you load it, it's already there so the console.log won't get called again.
