The AJAX call works fine in development mode but in production has  
issues.

The handler.call line in the following method is throwing error in the  
JavaScript console:

Error: handler has no properties

function createWrapper(element, eventName, handler) {  
var id = getEventID(element);  
var c = getWrappersForEventName(id, eventName);  
if (c.pluck(“handler”).include(handler)) return false;

```
var wrapper = function(event) {
  if (!Event || !Event.extend ||
    (event.eventName && event.eventName != eventName))
      return false;

  Event.extend(event);
  handler.call(element, event)
};

```

## Does anyone encountered this before? TIA.
