There is so much wrong there.
First off, all your functions are wrong. You define your scope function as empty, then redefine the controller function in angular (at least that's the effect in my browser using the referenced scripts in your jsfiddle).
look:
app.controller("myCtrl",function($scope){
});
Your phonenumber keybinding is the same, but the function that sets it up is never run anyway.
You don't set the controller or app in your div, either
Look, just examine this. It's mostly fixed but I didn't spend much time
