Metro App - Binding error on field "id"

After Visual Studio 2012 was launched one of the first things that I tried was to write a Metro App in Java Script. I started to write an application that get an Azure Table content and display it in a grid. Of course to be able to display data from a source we need to define a data structure.
So, I started to define a list with some items that I binding to the UI.

var myItems = [
 { id: 1, name: "Tom", age: 20},
 { id: 2, name: "Jack", age: 23},
 { id: 3, name: "Maria", age: 19},
];

After I bounded the data to the UI I hit F5 and surprise. Visual Studio hit me with an error that doesn’t give you any kind of information about the cause of the error.

{
  "exception":null,
  "error":
  {
    "description":"Null item"
  },
  "promise":
  {
    "_value":
    {
      "description":"Null item"
    },
    "_isException":false,
    "_errorId":3
   },
   "id":3
}

This error is thrown by terminate application handler function. Because of this we cannot see any information about the exact line of the error. In the first moment I checked to see if the id field is null or if I bounded correctly, but everything seems to be okay.
The next thing that I tried was to rename the id field to something else. In my case I replaced with a field named “key”. When I hit F5 I was surprised that everything was up and running.
In conclusion, when you are using data that are binding to the UI, don’t use reserved names for the fields like “id”.
