Another solution would be to use a directive that watched the model for any changes instead of using ng-change.

app.directive('onModelChange', function($parse){
    return {
        restrict: "A",
        require: "?ngModel",
        link: function(scope, elem, attrs, ctrl) {
            scope.$watch(attrs['ngModel'], function (newValue, oldValue) {
                if (typeof(newValue) === "undefined" || newValue == oldValue) {
                    return;
                }
                var changeExpr = $parse(attrs['onModelChange']);
                if (changeExpr) {
                    changeExpr(scope);
                }
            });
        } 
    };
});

Then you would use it like so:
