  1. // The code below is written in Typescript but I am still using Angular 1.x, not Angular 2.x
  2. // I don't like using $rootscope.broadcast.  It feels to heavy handed.  Is there a better way to pass data back from the service to the controller.  Right now I have to return the "totalCount" variable.  Could I be using Promises better to return control to the Controller?
