I’m trying to debug ko (version: 2.2.1) using

 tag:

but I'm getting this:

Uncaught Error: Unable to parse bindings.
Message: TypeError: Object object has no method 'getType';
Bindings value: text:ko.toJSON($root,null,2) 

UPDATE:

It seems like the $root object is actually the windows object, why is it happening, how can i make sure it remains in the scope of my ViewModel?

The scenario is like this:

I have a view that contains also a popup template. When a user clicks a button the popup shows and that is when I get this error (the $root looses the ViewModel scope and becomes the window object).

VIEW:

        Done 
        
        //THIS OPENS THE PROBLEMATIC POPUP
        
        

        
        
        

        
            

VIEWMODEL:

  /**
 * The module for the common Entities ViewModel
 */
define(['ko', 'komap', 'kopost', 'ca', 'sp/utils', 'sp/db'], function (ko, komap, kopost, ca, util, db) {

    /**
     * The Entities ViewModel.  This VM just exposes a collection of entities in a single property.
     * The model to retrieve is obtained from the last portion of the URL path.
     */

    function EntitiesViewModel(ctx, data) {
        this.init(ctx,data);

    }

    // EntitiesViewModel.prototype = new ca.ViewModel({});

    // EntitiesViewModel.prototype.constructor = EntitiesViewModel;

    ko.utils.extend(EntitiesViewModel.prototype,(function(){



        init = function(ctx,data){
