Focus event in Ember.Select view

I used Ember.Select viewas follows.

{{view "select" content=people
                optionLabelPath="content.fullName"
                optionValuePath="content.id"
                prompt="Pick a person:"
                selection=selectedPerson}}

Now I want to add an focus-out="showErrors"event listener to this kind of selection in order to handle some validation. This works great with Ember.TextField and Ember.TextArea. But I noticed that it focus-outdoes not work with the Ember.Select view.

It would be very nice if someone can solve the problem of this problem

Could you add an observer to selectedPerson so that when the value of the dropdown value changes, it triggers your check.

Older syntax:

validatePersonChange: function(){
   //do validation here
  }.observes('selectedPerson')

New syntax:

const { observer } = Ember;
...
validatePersonChange: observer('selectedPerson', function(){
    //do validation
  })
