Specify custom behavior on blur event.
A blur event fires when an element has lost focus.
Note: As the blur event is executed synchronously also during DOM manipulations
(e.g. removing a focussed input),
AngularJS executes the expression using scope.$evalAsync if the event is fired
during an $apply to ensure a consistent state.
