<tbody>
{{#each}}
<tr class="people-list">
<td>
<input type="checkbox" class="toggle">
{{#if isEdit}}
{{input type="text" valueBinding="Name" name="Name"}}
{{else}}
<label class="category-text">{{#linkTo 'category' this}}{{Name}}{{/linkTo}}</label>
{{/if}}
<img class="table-img" src="images/x.png">
<img class="table-img" {{action 'edit'}} src="images/pencil-grey.png">
</td>
</tr>
{{/each}}
</tbody>

actions: {
edit:function(){
this.set('isEdit', true);
}
}
