I have a multidimensional array that I am creating from a JSON Ajax call to my DB.

With in my Web App, I am trying to dynamically add a new row to the array using javascript along the lines of:

```js
list[new_row_id].item_id = new_value ;
list[new_id].item_title = new_title  ;

```

Clearly I am doing something wrong.

Any guidance would be appreciated.
