JavaScript How to override jQuery promise callback

I've created a convenience method that adds a default error handler for my ajax calls:

function myAjaxFunction(url, data) {

    return $.ajax({
        url: url,
        data: data

    }).fail(myErrorHandler);

}

So far, this works great, because now I don't have to specify the error handler function in 50 different places.

But sometimes I need to override the default error handler with a custom one. When I do this, however, it calls both error handlers:

myAjaxFunction("myurl", "mydata").fail(myCustomErrorHandler).then(doSomething);

How do I get it to override or remove the previous error handler from the chain?
