Is there a way to pass data to a change event via jQuery's trigger method?

The issue here is that a click event triggers the upload menu. Once the image is selected, the change event is fired, however. The data I passed into the trigger event's second parameter is passed to the click event, not to the change event. In the example below, data is undefined.

Trigger Image Change

$('.change_main_image').live('click', function() {

    $('input[name=photo].change_uploader').trigger('click', [some string]);

});

Event Handler

$('input[name=photo].change_uploader').live('change', function (e, data) {

   alert(data); // undefined

   //canvas resize and upload script

});
