This bug occurs when we type the number of the page in the pagination control. Just after that, if we click on the next page button, the number of the page is handled as a string and the +1 sum is done in a wrong way. For example, if we type 5 on the page number textbox, clicking on the next page button will take us to the 51th page, not the 6th.
I've recorded the behavior and we can see it in the image below.

One way we've found to deal with this problem is changing the code below, converting the value of the "page" variable to number, using the parseInt function.
self.pageForward = function () { var page = self.config.pagingOptions.currentPage(); self.config.pagingOptions.currentPage(Math.min(parseInt(page) + 1, self.maxPages())); };
I'm using Chrome version 62.0.3202.75.
