There are event handler and link like as below.

1. index.html

document.addEventListener(‘tizenhwkey’, function(e) {
  if(e.keyName == “back”){
     tizen.application.getCurrentApplication().exit();
  }
});

window.open(“new_window.html, “_self”);

2. new_window.html

document.addEventListener(‘tizenhwkey’, function(e) {
  if(e.keyName == “back”){
     history.back();
  }
});

I opened new HTML page using “window.open” and go back to index.html when back key event fired.

But back key event is not fired on “index.html”

How can I fix this issue?
