Почему это не работает ?

jQuery('input:radio[name=communication_level]').filter('[value=1]').attr('checked', true);

<div id="commLevelDialogForm" style="display:none;">
	<form id="cldf">
		<label><input type="radio" name="communication_level" value="4" />Please e-mail me relevant offers once they become available</label><br />

<label><input type="radio" name="communication_level" value="2" />Please e-mail me about your special offers less frequently - maximum once per month</label><br />
<label><input type="radio" name="communication_level" value="1" />I only want to receive service messages in the future</label><br />
<label><input type="radio" name="communication_level" value="3" />I do not want to receive e-mails from Optimalprint</label><br />
	</form>
</div>
