Can any change be implemented with binding structure on binding structure as if it is binding? What do I mean if I have

  & lt; Active Data A Knockout is observable and when I change it I have a transition effect as if some progress is shown with the ringing routing process.  
 Here's how my view-model  
  import To = essential ('peek'); class shell imdl implements {activate: (references: object) => zero; act View: Knockout oblobil & lt; any & switch; switchview: () => Zero; creator () {this.activate = this._activate callback; this.ActiveView = to.voreswable & lt; string & gt; 'Parts / welcome'); switch.viewview = this._activateView;} Private _activateView () {this.ActiveView ('About / about');} Private _activate callback (ctx: object) {}} export = shell;  
 

Changes work with any compulsive type. However, an error in your syntax It should look like this:

  & lt; Div data-bind = "type: {model: activeview, transit: 'login'}" & gt; & Lt; / Div & gt;
