Trouble with ember model and computed properties

I have a book model that i use a mapBy() computed property on to retrieve all the prices in the model. allPrices: mapBy('books', 'price'); Then i use max() to get the highest value. maxPrice: max('allPrices'); That part works as expected. The problem i have is that i want to display the max price AND the title of the book associated with that price but i cant figure out how to do it.

<h2>Max book price:  </h2>
<h2>Which belongs to the book  </h2>

How can this be achieved? Any help would be appreciated.
