 $("#cbpre").checked = true;

But it is not scoring, I've debugged, and it goes into this part, it just does not checkbox.

You can use the attr method or the prop method of JQuery for this:

$('#ck1').attr('checked', 'checked');
$('#ck2').prop('checked', true);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><p>Checkbox1:<inputid='ck1'type="checkbox" />
</p>
<p>
   Checkbox 2: <input id='ck2' type="checkbox" />
</p>
