title: android 2 way data binding example don't work as described
body: <p>I read <a href="https://halfthought.wordpress.com/2016/03/23/2-way-data-binding-on-android/" rel="nofollow">this article</a> about 2 way android data binding</p>
  
  <p>I noticed that code is a bit vague and decide to implement workable example and put it on github, so other guys will be much easier to dive in it. But going according instructions provided in this article I wasn't able make it work.</p>
  
  <p>In my example I just have main activity with switcher, and custom control, also with switcher. So, when I checking main switcher it refresh all the stuff properly and work as expected, but however when I check/uncheck internal switcher, it dosen't affect main viewmodel and anything in activity - so 2 way binding not working. </p>
  
  <p>Please, help me find the reason why this happen and fix the problem.</p>

  <p>Code fixed and now worked as expected in Android Studio 2.2 beta 1 at least.</p>
