Auto grow textarea scrolling issue

Hello I have problem with auto grow textarea.
The auto grow textarea working very fine, the problem is the view scrolling.
The problem happens only in ion-scroll (overflow-scroll=“false”), without ion-scroll it’s working fine.

HTML:

<ion-content>
    <form name="comment.form" ng-submit="submitComment()">
        <textarea ng-model="comment.data.content" auto-grow></textarea>
    </form>
</ion-content>

Javascript:

angular.module('myapp')
.directive('autoGrow', autoGrow);

autoGrow.$inject = [];

function autoGrow() {
    return {
        restrict: 'A',
        require: 'ngModel',
        scope: {
            ngModel: '='
        },
        link: function(scope, element, attr) {
            var update = function() {
                element.css("height", "auto");
                var height = element[0].scrollHeight;
                element.css("height", element[0].scrollHeight + "px");
            };
            scope.$watch('ngModel', function() {
                update();
            });
        }
    };
};

Hey!
I’ve the same problem in my Ionic 1.2.1 app. Do you have a solution for this?
