Android DialogFragment onViewCreated not called

This is how I make sure onViewCreated is called in kotlin:

class MyDialog: DialogFragment() {

    private lateinit var dialogView: View

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        dialogView = LayoutInflater.from(context).inflate(R.layout.dialog, null)
        val dialog = MaterialAlertDialogBuilder(context!!)
                .setView(dialogView)
                .create()

        return dialog
    }

    // Need to return the view here or onViewCreated won't be called by DialogFragment, sigh
    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        return dialogView
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        // Yay it's now called!
    }

    override fun onDestroyView() {
        dialogView = null
        super.onDestroyView()
    }
}
