Is there a clever way to listen to specific properties in an array-model in Angular.js?

Let's say I have a model that looks like this:

[
    {
        label: "Hobbit 1",
        isbn: 10
    },
    {
        label: "Hobbit 2",
        isbn: 20
    },
    {
        label: "Hobbit 3",
        isbn: 30
    },

]

Is there a clever way, in Angular, to listen for any label changes and if so, get the isbn in an easy way?

The only way I know is to put up a $scope.$watch( model, function( new, old ) { ... on the whole model and then compare, by looping through all the items and comparing the label property against the previous version of the model. But there has to be a more clever way?
