I have problem with Cake PHP delete javascript confirmation dialog.

I am using this code:

<td><?php echo $this->Html->link('Delete',

                                        array('controller' => 'RealEstate', 'action' => 'delete',$r['RealEstate']['id']),

                                        array('onclick'=>'return confirm(Are you sure?);'))?> </td>

and this produce html:

<td><a onclick='return confirm(Are you sure?);' href=/cake1/RealEstate/delete/65>Delete</a> </td>

as you can see this produce wrong Html.

How to fix this ?

FIXED:
Problem was in back slashes Are you sure?, just removed and this works well Are you sure?
