ngModel directive is not usable on file input.

If you don't care about being in debugInfoEnabled on prod, you can pass it true like this in your app.js.

$compileProvider.debugInfoEnabled(true);

You then will be able to access your scope from your html. In you file input just add :

onchange="angular.element(this).scope().yourChangeFunction(this)

You can access your file in your js code with :

scope.yourChangeFunction = function(element){scope.file=element.files[0];}
