Firing an overriden click event

Firing an overriden click event

I need to put a confirmation message for all delete buttons on my website. Upon clicking a delete button, I want a modal popup to appear asking for confirmation like this:

$(".delete-button").click(function(){
        ShowModalConfirmation("Are you sure you want to delete this item?", deleteButtonOriginalClickFunction);
        return false;
});

The ShowModalConfirmation will show a modal popup and if the user clicks "Ok", then it will execute the whatever function I pass in the second parameter. So my question is how can I pass to the ShowModalConfirmation the original click function (with the original context) as the second parameter?
