GetCell Button Event problem

Hey All,

I'm very new to Xamarin, and though there are some threads that seem to deal with similar issues, I am having a heck of a time getting a VERY simple custom button added to my UITableViewCell without its TouchUpInside event causing the horrible crash that everyone has run into. I would great appreciate any advice as to what exactly I'm doing wrong here. Thanks in advance!

        // Customize the appearance of table view cells.
        public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
        {
            var cell = (UITableViewCell)tableView.DequeueReusableCell (CellIdentifier, indexPath);

            cell.TextLabel.Text = objects [indexPath.Row].ToString ();

            var button = new UIButton (UIButtonType.System);
            button.TouchUpInside += (sender, e) => 
            {

// var buttonCell = ((UIButton)sender).Superview as UITableViewCell; string s = "string"; // var cellIndex = tableView.IndexPathForCell(buttonCell); // var objectInstance = objects[cellIndex.Item]; };

            button.SetTitle ("Submit", UIControlState.Normal);
            button.Frame = new System.Drawing.RectangleF (150.0f, 5.0f, 150.0f, 30.0f);

            cell.AddSubview (button);

            return cell;
        }
