Programming Strategy for ASP.NET MVC 5 - Updating a Child or Related Records on Same Page - asp.net

Question

I am struggling a bit with strategies that allow for updating child records related to a parent record in MVC in the same view. Take for instance model classes described below.
public class Person {
public Person() {}
int personId{get;set;}
string personName{get;set}
public virtual ICollection<Phone> Phones { get; set; }
}
public class Phone {
public Phone() {}
public int PhoneId {get;set;}
public string PhoneType {get;set;}
public string Number {get;set;}
public string Ext {get;set;}
}
Providing a single page view allows for Creating,Updating,Deleting a person easily.
Adding actions that jump to views designed specifically for the phone records and then return the user to the person record is also straightforward.
What is the best strategy for displaying the related phone records for the person in the same view as the person information and allowing for the CRUD operations to be used against only the phone entities in the same view?
If the answer is that AJAX is the best approach then that is perfectly acceptable. I am looking for feedback from the community that describes what individuals have used in this type scenario in their projects that have this type of challenge.
There was one approach listed here:
http://www.codeproject.com/Articles/786085/ASP-NET-MVC-List-Editor-with-Bootstrap-Modals
That had a decent if somewhat cumbersome approach.
I have to believe that this is a much simpler problem and that I am quite literally missing the obvious.

Answer 1

I've done in-line editing by displaying the current phone information and having hidden inputs. When the user clicks the edit button, I toggle visibility to hide the display and show the inputs.
I've also done similar to the article. Have a modal popup to edit phone numbers, after saving the changes and closing the modal refresh the partial with the phone number list.
In either scenario I'm just submitting an ajax request and return a partial that I use to replace the div that contained the original information.
The modal dialog seems to be little more "modern".
