_findCallback unexpectedly dropping options when moving to custom function

[twolfson]

I wanted to add a wrapper around the $.ajax invocation via a custom method. However, as soon as I switch to my custom wrapper, then I lose the callbacks.save.options I was previously setting. After debugging, it looks like that is intentional behavior in _findCallback. Can we please make it consistently inherit options? I don't see why they need to be dropped.

	var _findCallback = function(callback, callbacks) {
	var cb = { options: {} }, callbackType = typeof callback;
	if (callbackType === "function") {
	// Custom function with no options
	cb.method = callback;
	} else if (callbackType === "string" && callbacks[callback]) {
	// Built in method, use default options
	cb.method = callbacks[callback].method;
	} else if (callbackType === "object") {
	callbackType = typeof callback.method;
	if (callbackType === "function") {
	// Custom function
	cb.method = callback.method;

	cb.options = $.extend(true, cb.options, callbacks[callback.method].options, callback.options);
	}
