webpack--watch not working

webpack --watch is not working but the webpack does,when I edit some changes in my js the watcher will not make any updates in my DOM(html) so I will have to restart(do webpack again) so that it will update the changes.

codes that might have the bug:

package.json:

`{
  "name": "samplereact",
  "version": "1.0.0",
  "main": "webpack.config.js",
  "dependencies": {
    "babel-loader": "^6.2.4",
    "babel-plugin-add-module-exports": "^0.1.4",
    "babel-plugin-react-html-attrs": "^2.0.0",
    "babel-plugin-transform-class-properties": "^6.9.0",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.5.0",
    "babel-preset-stage-0": "^6.5.0",
    "core-js": "^2.4.0",
    "react": "^0.14.8",
    "react-dom": "^0.14.8",
    "webpack": "^1.13.1",
    "webpack-dev-server": "^1.14.1"
  },
  "devDependencies": {},
  "scripts": {
    "dev": "./node_modules/.bin/webpack-dev-server --content-base src --inline --hot",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "description": ""
}
`

webpack.config.js: 

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');

module.exports = {
  context: __dirname + "/src",
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/scripts.js",
  module: {
    loaders: [
      {
        test: /\.js?$/,
        exclude: /(node_modules|bower_components)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015', 'stage-0'],
          plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy']
        }
      }
    ]
  },
  output: {
    path: __dirname + "/src/",
    filename: "scripts.min.js"
  },
  plugins: debug ? [] : [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false })
  ]
};

And my folder structure is this: enter image description here

I only put package.json and webpack.config.js here because I suspected that only one of them is the source why my watch is not working.

btw I followed this tutorial(https://www.youtube.com/watch?v=MhkGQAoc7bc) and even tho' I watched it 5 times,I cant still find the problem why this watch is not working.

You're probably running into webpack's sensitivity to path separators, which has bitten me numerous times.

The trick is to use path.sep or path.join instead of / when specifying your context. So you'd change this:

context: __dirname + '/src',
entry: './src/scripts.js',

to this:

context: path.join(__dirname, 'src'),
entry: './scripts.js',

Note that the entry point can still use ./, as it's resolved using require, but the context is what webpack uses for --watch (also, you had src in both context and entry, which I assume is redundant).
