The cells in my table view disappear as I scroll down Xamarin .ios

{
    Debug.WriteLine("TRYING TO CREATE CELL");
    if (UIApplication.SharedApplication.StatusBarHidden)
    {
        UIApplication.SharedApplication.StatusBarHidden = false;
    }
    this.numberLinesIncrease = 0;
    resize = false;
    var comment = (Comment)item;
    var cell = (CommentsCell)tableView.DequeueReusableCell(commentsCellIdentifier,indexPath);
    if (cell == null)
    {
        cell = new CommentsCell();
        //var views = NSBundle.MainBundle.LoadNIB(CommentsCell.Key,cell,null);
    }
    //textFont = cell.comment.Font;
    cell.comment.Text = comment.comment;
    //cell.comment.resizeLabel();
    cell.LayoutMargins = UIEdgeInsets.Zero;
    //Debug.WriteLine("RETURNING CELL" + cell.comment.Text);
    //cell.Frame = new CGRect(cell.Bounds.X, cell.Bounds.Y, cell.Bounds.Width * .8, cell.Bounds.Height);
    this.TableView.EstimatedRowHeight = 65f;
    this.TableView.RowHeight = UITableView.AutomaticDimension;
    return cell;
}
