code: function findScope(model, prop) {
      while (model[parentScopeName] &&
             !Object.prototype.hasOwnProperty.call(model, prop)) {
        model = model[parentScopeName];
      }
  
      return model;
    }
docs: Single ident paths must bind directly to the appropriate scope object. I.e. Pushed values in two-bindings need to be assigned to the actual model object.
