       Here, tells to look for a property named in the object contained
       in the request body. So when we send a request to , will use the
       property of the video object in the request body to set the
       parameter in the route. The third parameter of the method is
       used to extend the service. UPDATE: How: For some reason known
       only to the developers, you cannot send requests using the
       service by default. You need to extend it by adding an update
       method that uses . Next, we use to get the video with a given .
       This is to populate the form when the page loads.
       The first parameter of provides the value of the parameter in
       the route. We use , which gives us access to parameters in the
       browser's address bar. Remember the route declaration for the
       edit page? There, we used route parameters . Therefore, we can
       access it via . In the callback method of the video. , we fetch
       the video returned from the server and store it in . This way,
       the Phone Number List

       form will be automatically populated
       with our video object while the two-way binding of is running in
       the background. do you remember? We bind the input field to a
       property of the video object on . Any changes in the input
       fields will be reflected in and vice versa.

       Finally, in the body of the controller, we define a save method
       that will be called when the user clicks the save button. Note
       that here we use , not .   we defined earlier when extending the
       service. So this will make a request to our endpoint. We're
       almost done. Our new controller is ready. We just need to
       reference it in the routing configuration. Change the routing
       configuration as follows: Let's test this new functionality.
       Return to the browser and refresh the homepage. Choose one of
       the videos. Make some changes and click the Save button.
       Everything should work. In the next section, we'll add a feature
       to the Video Rental Store application to build out the full
       functionality.
