Change the text color,value and images in ember

I have designed the ember app in which I have photos feed page.Each pic contains like button,like test and value corresponding to it.Now when I click on the like button.It should change like pic,color of text like,and its value.it is same as Facebook like button.I am not sure how to implement it in ember

feed.js

{{#each feedResult as |feed|}}    
<div class="scale">
           <img id = "image1" src = "{{feed.feedPhotos.0.photo_url}}"/>
           <div class="transhifive">
            {{#if feed.feedPhotos.0.is_liked}}
                <a href = "#" {{action 'unlike'}} >
                   <img  src = "images/ic-unlike-yellow.png">
                   <p>Hi Five! |</p>
                </a>
            {{else}}  
                <a href ="#" {{action 'like'}}>
                   <img src = "images/ic-like-white.png"/>
                   <p>Hi Five! |</p>
                </a>
            {{/if}} 
            <p>{{feed.feedPhotos.0.numlikes}}</p>
</div>
{{/each}}

controller.js

export default Ember.Controller.extend({
     session:service('session'),
     feedResult:Ember.computed('model',function() {

       "SOME MANIPULATION WITH MODEL DATA"

}),
hifive(){
        this.incrementProperty('feed.feedPhotos.0.numFives');
    }
  }
});

I thought this will atleast increase the like value but it is also throwing error.

Uncaught Error: Property set failed: object in path "feed.feedPhotos.0" could not be found or was destroyed

How should implement it so that it work exactly like facebook "like button"?
