You could add a delete action to your IndexController:
App.IndexController = Ember.ArrayController.extend({
actions: {
register: function() {
this.pushObject({
'first' : this.get('firstName'),
'last' : this.get('lastName')
});
},
delete: function(person) {
this.content.removeObject(person);
}
}
})
Then add the following to your index.html:
{{#each}}
<tr>
<td>
{{this.first}}
</td>
<td>{{this.last}}</td>
<td>
<button {{action "delete" this}}>X</button>
</td>
</tr>
{{/each}}
