Ember.js - Controller not picking model data

Question

I have a model which has this field

diaryItemLabel: DS.attr('string'),

I want to access the data from this field in my controller.

Controller.js

I want to replace the 'Add' with whatever data I get from diaryItemLabel.

I cannot use this.get('model.diaryItemLabel'). It gives me this.get() is not a function. I tried using Ember.get('model', 'diaryItemLabel'). It gives me empty string.

Edit 1: Set default to 'Add' if model.diaryItemLabel variable is empty.

Could someone guide me to the right direction?

Thanks

Controller will get model property only after setupController hook which will be called after model hook.

Create computed property which dependant on model.diaryItemLabel in controller which will return your required object

confirm:Ember.computed('model.diaryItemLabel',function(){
 let temp = {};
 temp.accept= { text: Ember.isEmpty(this.get('model.diaryItemLabel')) ? 'Add' : this.get('model.diaryItemLabel'), buttonClass: 'btn btn-primary'};
 temp.reject = { text: 'cancel', buttonClass: 'btn btn-default'};
 return temp;
}

Also can you tell me how do I set the temp.accept text default to 'Add'. So if model.diaryItemLabel is empty, then set it to 'Add'
