<input type="text" ng-model="expiry.year" />
<input type="text" ng-model="expiry.month" />
<input type="text" ng-model="expiry.date" />

{{ expiration }}

You can setup a watch in your controller

$scope.$watch('expiry', function(newVal) {
    $scope.expiration = newVal.year + '-' + newVal.month + '-' + newVal.date
}, true);

not a complete solution but you can work along these lines

<input type="text" ng-model="expiry.year" ng-change="expiration = expiry.year + expiry.month, expiry.date" />
<input type="text" ng-model="expiry.month" ng-change="expiration = expiry.year + expiry.month, expiry.date"  />
<input type="text" ng-model="expiry.date" ng-change="expiration = expiry.year + expiry.month, expiry.date"  />

it does not handle undefined etc case. better would be to write a function and do the concatenation in controller...

<input type="text" ng-model="expiry.year" ng-change="expirationUpdated()" />
<input type="text" ng-model="expiry.month" ng-change="expirationUpdated()" />
<input type="text" ng-model="expiry.date" ng-change="expirationUpdated()" />

do it in function

var expirationUpdated = function() { ///concate logic here}
