Empty the form & setPristine

The $setPristine was not working as intended because the $scope.talk = {} was discovered by angular after it was called. Thus the form was modified after & marked dirty. At least I believe this is what happened. One way to do this is to call $setPristine after the digest. It could be achieved using $watch.

I propose to try something like :

// We do not try deep inspection on talk to not be informed of changes
// of attributes' values
$scope.$watch('talk', function(talk) {
  // If the talk object is not empty, do nothing
  if (talk) return;
  // Set form as pristine
  $scope.form.$setPristine();
});
