Angular Scope Binding Support in Toolbar Template

I would like to use angular bindings in the toolbar template in the Gantt chart which does not seem to work. Please see dojo for example: http://dojo.telerik.com/ILiyu 

The particular point of interest is:

            $scope.foo = " [foo from scope] ";

            $scope.ganttOptions = {
                toolbar: [
                    {
                        template: "{{ foo }}"
                    }
                ]
            };

Thanks
