UI Kit View in SC20: appending a new view.

scroll_view.js

  createScrollView: function() {

       var parentView = this 
        , view = null 
        , childViews = get(parentView, 'childViews') // otherwise return null when parentView.childViews
        , buffer
        , fragment;

    view = parentView.createChildView( SC.View.extend(), {
      classNames: ['scroll-scroll-view'], 
      elementId: this.scrollerId
    });


    buffer = view.renderToBuffer().string();
    fragment = SC.$(buffer);

    view._notifyWillInsertElement();

      parentView.$().append(fragment);
      childViews.push(view);

    view._notifyDidInsertElement();

    // How can view change its state from inBuffer to inDOM (to access $() ) ????


  },

is there any other way to handling child views in SC 20?

1. it could be easier if a command like: this.createChildView( newView, {}); would complete the process of adding a view and append it to the dom.

2. Also wondering how the view change its state from inBuffer to inDOM, to be able to access view.$().

Any suggestions/discussions will be really appreciated?
