So i am trying implementing collectionView inside tableviewCell and i get a weird behaviour after fetching data.

This is the tableViewCell:

class PortfolioPieTableViewCell: PortfolioBaseCell {
@IBOutlet weak var pageControl: UIPageControl!
@IBOutlet weak var collectionView: UICollectionView!

private var disposeBag = DisposeBag()

override class var identifier: String {
    return "PortfolioPieTableViewCell"
}

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func prepareForReuse() {
    super.prepareForReuse()
    disposeBag = DisposeBag()
}

func config(viewModel: PortfolioPieTableViewViewModelCell) {
    collectionView.register(UINib(nibName: "PortfolioPieCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "PortfolioPieCollectionViewCell")

    viewModel.items.debug("PortfolioPieTableViewViewModelCell
