var paperHandler = function(event) {
	if(!event.target.value) {
		value = event.target.checked;
	} else {
		value = event.target.value;
	}
	$scope.$apply(function() {
		$scope.workOrder[event.target.getAttribute("ng-model")] = value;
	});

};


var fields = document.querySelectorAll('paper-input');
for (var i = 0; i < fields.length; ++i) {
	fields[i].addEventListener('change', paperHandler);
}

fields  = document.querySelectorAll("paper-checkbox");
for (var i = 0; i < fields.length; ++i) {
        fields[i].addEventListener('change', paperHandler);
}

Stuff this in your controller, and change $scope.workOrder to wherever you want to put the objects.

It should be "future-compatible" because it allows you to still specify variables with ng-model.
