Answer 1

The example in the docs shows the event listeners — even the deviceready — being attached after the document onload event has fired.

Using your code:

function onDeviceReady() {
  document.addEventListener("backbutton", function (e) {
    e.preventDefault();
    console.log("hello");
  }, false);
}

document.onload = function () {
  document.addEventListener("deviceready", onDeviceReady, false);
};

Finally found the answer on this Ionic Forum thread:

$ionicPlatform.registerBackButtonAction(function () {
  if (condition) {
    navigator.app.exitApp();
  } else {
    handle back action!
  }
}, 100);

$ionicPlatform.registerBackButtonAction allows to completly overwrite back button behavior. First param is a callback function and the secondone a priority (only the callback with the highest priority gets executed).
