Подгрузка данных RecyclerView | Kotlin

Помогите решить проблему, ибо у меня мозг не работает. Читал пост, но что-то ничего не получается.

Есть Adapter

class Adapter() : RecyclerView.Adapter<Adapter.ViewHolder>() {
var list: MutableList<Item> = mutableListOf<Item>()
var loader: Boolean = false

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
    val inflater = LayoutInflater.from(parent.context)
    return ViewHolder(inflater, parent)
}

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    val i: Item = list[position]
    holder.bind(i)
}

override fun getItemCount(): Int = list.size

fun set(c: MutableList<Item>) {
    this.list.clear()
    this.list.addAll(c)
    notifyDataSetChanged()
}

class ViewHolder(inflater: LayoutInflater, parent: ViewGroup) : RecyclerView.ViewHolder(inflater.inflate(R.layout.b_y_m_a_l_r_item, parent, false)) {
    private var image : ImageView? = null
    private var meta : TextView? = null
    private var title : TextView? = null
    private var genres : TextView? = null
    private var rating : TextView? = null
    private var ch_counts : TextView? = null

    init {
        image = itemView.findViewById<ImageView>(R.id.b_y_m_a_l_r_i_image)
        meta = itemView.findViewById<TextView>(R.id.b_y_m_a_l_r_i_meta)
        title = itemView.findViewById<TextView>(R.id.b_y_m_a_l_r_i_title)
        genres = itemView.findViewById<TextView>(R.id.b_y_m_a_l_r_i_genres)
        rating = itemView.findViewById<TextView>(R.id.b_y_m_a_l_r_i_rating)
        ch_counts = itemView.findViewById<TextView>(R.id.b_y_m_a_l_r_i_chCount)
    }
    fun bind(data: Item) {
        meta?.text = data.meta
        title?.text = data.title
        genres?.text = data.genres
        rating?.text = data.rating
        ch_counts?.text = data.ch_counts

        if(data.image != ""){
            Picasso.get()
                .load(data.image)
                .placeholder(R.mipmap.image_placeholder)
                .error(R.mipmap.no_internet)
                .fit()
                .networkPolicy(NetworkPolicy.OFFLINE)
                .into(image, object: com.squareup.picasso.Callback {
                    override fun onSuccess() {

                    }

                    override fun onError(e_p: Exception?) {
                        //Try again online if cache failed
                        Picasso.get()
                            .load(data.image)
                            .error(R.mipmap.no_internet)
                            .into(image, object: com.squareup.picasso.Callback {
                                override fun onSuccess() {

                                }

                                override fun onError(e: Exception?) {
                                    Log.v("Picasso", "Could not fetch image");
                                }
                            });
                    }
                });
        }

    }
}

override fun onViewAttachedToWindow(holder: ViewHolder) {
    super.onViewAttachedToWindow(holder)
    val layoutPosition = holder.layoutPosition

    loader = layoutPosition == itemCount-1
}

}

А во фрагменте я вызываю это:

GlobalScope.launch {
            val page = 1;
            vModel?.setPage(page)
            vModel?.setUrl("https://#####?Book_page=")
            vModel?.init()

            val elements = vModel?.filterElements()
            GlobalScope.launch(Dispatchers.Main) {
                if (elements != null) {
                    dataAdapter!!.set(elements)
                }
            }
        }

Вот ViewModel фрагмента:

private var URL : String? = null
private var doc: Document? = null
private var page = 0

fun init(){
    try {
        doc = Jsoup.connect(URL + page).get()
    } catch (e: IOException) {
        // TODO Auto-generated catch block
        e.printStackTrace()
    }
}

fun setPage(p : Int) { page = p }

fun setUrl(u : String){
    URL = u
}

@RequiresApi(Build.VERSION_CODES.N)
fun filterElements() : MutableList<Item>{
    val list = mutableListOf<Item>()

    return list;
}

@Suppress("UNREACHABLE_CODE")
@RequiresApi(Build.VERSION_CODES.N)
fun filterTitle(data: String, symbol: Char) : String{
    val index = data.indexOf(symbol)

    if(index == - 1) {
        return data
    } else {
        val result = ""
        val elements = data.split(symbol)

        for (el: String in elements){
            val cyrillic: Boolean = el.chars()
                .mapToObj(Character.UnicodeBlock::of)
                .anyMatch { b -> b == Character.UnicodeBlock.CYRILLIC }

            if (cyrillic) return el.trim();
        }
        return data
    }
    return data
}

Так как мне сделать подгрузку контента? У меня срабатывает onViewAttachedToWindow и loader меняется на true, но как мне подгрузить контент?
