Mouse hover with ember - ember.js

Question

I am new to Ember. I want when i hover the mouse over a .png file to be transparent and to exist there on the right corner an 'X' button and when you press it, it will be removed from the store. Any ideas or any example? I have these files:
showactivecamp.hbs
<style type="text/css">
.image {
width: 190px;
height: 190px;
opacity: 1;
}
.image:hover {
opacity: 0.3;
}
i.fa-remove {
#extend . image : hover;
color: #fff;
background-color: #808080;
background-color: rgba(0, 0, 0, 0.5);
position: absolute;
top: 8px;
right: 8px;
padding: 2px;
z-index: 1;
cursor: pointer;
}
</style>
<div class="thmb-prev">
<button type="button" class="fa fa-remove" {{action "removeCampaign" on="click"}}>
</button>
<img src="/assets/images/photos/media2.png" class="image" alt="">
</div>
controllers\showactivecamp.js
import Ember from 'ember';
export default Ember.ObjectController.extend({
needs: ['campaign'],
actions: {
removeCampaign: function (campaign) {
var camp = this.get('model');
camp.deleteRecord();
camp.save();
}
},
getactivecamp: function () {
return this.store.findAll('campaign');
}.property()
});
views\showactivecamp.js
import Ember from 'ember';
export default Ember.View.extend({
click: function (evt) {
this.get('controller').send('click', this.get('campaign'));
}
});

I believe something like this would be best handled with a CSS solution rather than creating the unnecessary views in Javascript

You posted your code but not mentioned about the issue. I am not sure what is the issue you are getting.
Have a look into this jsbin http://jsbin.com/xumomu/1. I have used FixtureAdapter.
UPDATE:
http://jsbin.com/xumomu/2/
I have wrapped image and close icon in a view called 'image'. X icon will be shown on mouse enter and will be hidden on mouse leave using jQuery.
As Ember guide says, Use View when you need sophisticated handling of user events.
I suggest you to go through documentation to get clear idea about View and Event handling in ember.
