AddEventListener Accepting Functions With Arguments?

I am trying to create a script that will cover cross-browser limitations in adding event listeners to elements. I have found plenty of resources to add a listener but can't find any way of assigning a function containing arguments. Here is what I have so far:

/* Attach events regardless of browser */

function addEvent(obj, evType, fn)
{
if (obj.addEventListener)
{
obj.addEventListener(evType, fn, false);
return true;
}
else if (obj.attachEvent)
{
var r = obj.attachEvent("on"+evType, fn);
return r;
}
else
{
return false;
}}

/* Contains all attachments to be made on page load */

function load()
{
item = document.getElementById('toggleControl');
addEvent(item, 'click', toggle);

item = document.getElementById('alertLink');
addEvent(item, 'click', runAlert);
}

/* Add event to page load and assign load() function */

addEvent(window, 'load', load);

The actual functions for toggle and runAlert are in a seperate .js file, but are standard functions. the problem is that I can't find a way to perform the equivalent of:

item = document.getElementById('toggleControl');
addEvent(item, 'click', toggle('toggleID'));

It simply does not work.
