Passing a Blaze Template as a Parameter to a function creates Famous.js surface

Question

I am trying to update my famous.js surfaces' content by using Meteor's Blaze.toHTMLWithData(template, data), like Blaze.toHTMLWithData(Template.roomIlanSpecsTemplate, data), with a custom template in a function creating a famous surface inside a famous view. I want to pass the template in the cursorToArray function depending on the type of document returned to its callbacks. But I cannot have a rendered page on the browser, even there is no error in the console. If I use hardcoded version like having createFn function for each different template and then defininig and cursorToArray fucntion with that function it works.

What can be the thing I miss here?

    cursorToArray = function(cursor, renderablesArray, template, createFn){
    //each callback should decide which createFn to use based on result document, cos each result has a different template so a createFn.
    cursor.observe({
    addedAt: function(document, atIndex, before) {
        renderablesArray.splice(atIndex, 0, createFn(document, template));//createRoomIlanView, createRoomRenterIlanView, createFriendLookupIlanView
    },
    changedAt: function(newDocument, oldDocument, atIndex) {
        renderablesArray[atIndex] = createFn(newDocument, template);
    },
    });
}
cursorToArray(Ilans.find(), ilanViews, Template.roomIlanSpecsTemplate, createIlanView);

portion of the createFn definiton:

function createIlanView(data, template){
        var ilanSpecsSurface = new Surface({
          content: Blaze.toHTMLWithData(template, data), 
          properties: {
            fontSize: "14px"
          }
        });

        return ilanSpecsSurface;
    }

If it is all about older Famous what about using Reactive Surface from https://stackoverflow.com/a/30445791/2288496

var ReactiveTemplate = famodev.ReactiveTemplate;


var reactive = new ReactiveTemplate({
   template: Template.mytemplate,
   data: Collection.find().fetch(),
   properties: {}
});

A good example how to implement Routing, Subscriptions etc. https://github.com/sayawan/flowwy
