Ember list of checkbox on check one send rest

I have a list of checkboxes in my template:

<table>
                    <thead>
                    <tr>

                        <th></th>
                        <th>Sender</th>
                        <th>Title</th>

                    </tr>
                    </thead>
                    <tbody>

                    {{#each message in model.entities}}

                        <tr>

                            <td class="cell-star">
                                {{input type="checkbox" name=message.id tabindex=message.id class="starBox" checked=message.isStar }}

                            </td>
                            <td class="cell-broadcaster">
                                {{message.notification.autor.firstName}} {{message.notification.autor.lastName}}
                            </td>
                            <td class="cell-title">
                                {{#link-to 'notifications.details' message.notification.id}}{{message.notification.title}}{{/link-to}} {{#unless message.isRead}} (new) {{/unless}}
                            </td>

                        </tr>

                    {{/each}}

                    </tbody>
                </table>

And now i want to send rest query every time when i change some of the checkbox state with id of changed checkbox. What should i write in my controller?

i have tried something like that but i cannot get data of changed checkbox:

updateStarStatus: function() {

   console.log('checkbox clicked');
//here should be something like that:
//$.getJSON(apiHost + "/api/forum/star/"+id);

}.observes('model.entities.@each.isStar'),

im not using emberData. My model looks like this:

model: function() {
          return  $.getJSON(apiHost + "/api/forum");

},
