Meteor & Polymer Data Binding

help

I am trying to bind array fetched from Mongo to Polymer webcomponent

  Polymer({
    is: 'project-collection',
    properties: {
      items: {
        type: Array,
        value: Projects.find({}).fetch(),
      }
    },
...

I also tried some variations, I made function objectCollectionSync() to listen changes in Mongo

objectCollectionSync = function(mongoCollection, callback) {
  callback(mongoCollection.fetch());
  mongoCollection.observe({
      added: function() {
        callback(mongoCollection.fetch());
      },
      changed: function() {
        callback(mongoCollection.fetch());
      },
      removed: function() {
        callback(mongoCollection.fetch());
      },
      movedTo: function() {
        callback(mongoCollection.fetch());
      },
  });
}

and using of objectCollectionSync() in Polymer webcomponent

ready: function() {
      objectCollectionSync(Projects.find({}), function(result) {
        this.items = result;
      });
    },

With <project-collection item="{{ stringify projects }}"></project-collection> it works fine, but it seems like a dirty solution. I want to build whole application with webcomponents with just a little bit of Blaze. Is there any non hacky solution?
