title: Cannot read property 'bind' of undefined. React.js
body: <p>I'm making list using onsenui and react.
  but I cannot call a bind from onchanged.</p>
  
  <p>I couldn't figure out.... Does anyone can solve this?</p>
  
  <p>this is my code.
  I'd like to call handlechanged method from input item.
  But then,  Cannot read property 'bind' of undefined is raised.</p>
