   # Bug Report
   
   ## Problem
   message event fires only once for one inAppBrowser window
   ### What is expected to happen?
   Every time when postMessage is executed in inAppBrowser window, message would be sent and received by message event listener.
   
   
   ### What does actually happen?
   Only first message is received by message event listener.
   
   
   ## Information

   ### Command or Code
   <!-- What command or code is needed to reproduce the problem? -->
   This is code from remote web page that is opened in inAppBrowser:

       var href = $(this).attr('href');
        e.preventDefault();
       console.log('sending message', href);
       webkit.messageHandlers.cordova_iab.postMessage(JSON.stringify({url: href}));
       return false;
    });
   ```
   Code in application that calls inAppBrowser window and listens to message event:
   ```
   element.on('click', function(e) {
       e.preventDefault();
       var browserWindow = cordova.InAppBrowser.open(element.attr('href'), element.attr('target'), 'location=no,zoom=no');
   
       browserWindow.addEventListener('message', function(params) {
           console.log('params', params);
           if (params.data.url) {
               cordova.InAppBrowser.open(params.data.url, '_system');
           } 
       });
   
       return false;
   });
   ```
