Ionic live reload feature not reloading application

I tried to use live reload feature with ionic serve and ionic emulate ios --livereload. Server starts well, application is displayed on simulator (or in browser) and it works smoothly.

When I change a file (a js or html in www directory) and save it, console write HTML changed: www/index.html for example, but application doesn't reload itself as it should be.

I supposed that websocket between server and app could be broken, but when I kill the server (Ctrl-C), web inspector immediatly fire the following error : [Error] WebSocket network error: The operation couldn’t be completed. Connection refused (192.168.5.2, line 0, x4)

So I supposed that there is no issue with websocket. Moreover, it is displayed with no error in Network pane of web inspector.

Is there something I missed to made livereload work ?

My configuration :

  • Cordova CLI: 5.0.0
  • Ionic Version: 1.0.0
  • Ionic CLI Version: 1.4.5
  • Ionic App Lib Version: 0.0.22
  • ios-deploy version: 1.7.0
  • ios-sim version: 3.1.1
  • OS: Mac OS X Yosemite
  • Node Version: v0.10.30
  • Xcode version: Xcode 6.3.2 Build version 6D2105

Don't hesitate to ask me for clarification if something is not clear.

Edit

I also tested it without Internet connection at all to check if it was a firewall issue or something like that, but it changes nothing.
