How to reference a model in Ember.js? -

I am working through the DOOMVC and in the code given below, just do not understand that It refers to var model = this.get ('model'); .

Does it refer to controller or root if this is the controller , then where do we go from Does the model work with x controller y ?

  Todos.Dad Controller = Amber.Object Controller Adended ({complete: function (key, value) {var model = this.get ('model'); ...} .property ('Model.isCompleted')});    
 
 
  I  Usually  this  inside  amber.office  function means that  Ember.Object  (code  Todos.TodoController An example of ). / P> 
 Example:  
  App. Some RURTE = M. Route.ex ({active: function} (this; // this is the app. Some root frequency reference.}}); App.SomeController = Em.Controller.extend ({someMethod: function () {this ; // This is the app. Some controller example referees.}};; App.SomeView = Em.View.extend ({someMethod: function () {this is; // This app is a example example ref.}});   
 and so on.  
  II.   this.get ('model')  is just a property Controller (if you want you can set any value for that property) * A Prior to end v1.7, the  model  was a  ember.computed.alias  which was on the property of a controller called  content , but this latest amber version In behavior./P> 
 another  model  property, in  Em.Route , it is different from  Em.ObjectController.model  Actually, this is the function to be applied in routing order, which gives data, which  Em.Route  a  controller.model  to  hook Use to set property  em in C does .Route . Therefore, the output of  this.get ('model')  inside  Em.Route  will be a function.  
 P. s. I tried, but I think I have not succeeded. :) I'am sorry.
