argument event cause error onPageClick

If using event like event.preventDefault() in onPageClick method,
it will case error when use the api $(selector).pagination('selectPage', pageNumber);

Because selectPage will not pass the event to the _selectPage.

Start by tracing the onPageClick callback and the selectPage API through the _selectPage entry point. Reproduce the issue with event.preventDefault() and $(selector).pagination('selectPage', pageNumber), then verify that the API path handles the event consistently without raising an error.
