Check All Function Not Working?

I have a webpage with a single form. Under that form I have two separate lists of checkboxes. One set is called eventList the other is assigneeList.I have added two other checkboxes, one is as follows,

Code:

<input name="checkAllEvents" type="checkbox" id="checkAllEvents" onclick="checkAll(this.id, 'eventList')" />

The other is,

Code:

input name="checkAllDelegates" type="checkbox" id="checkAllDelegates" onclick="checkAll(this.id, 'assigneeList')" />


What I want to do is, check all the assigneeList boxes with the same value as the checkAllDelegates checkbox. And the same go the other set respectively.Through rummaging around I came up with the following,

Code:

<script type="text/javascript">
$(function checkAll(id, name) {
$("INPUT[@name=" + name + "][type='checkbox']").attr('checked', $('#' + id).is(':checked'));
});
</script>

However nothing seems to happen when I check the boxes, what am I doing wrong?
