PageView addpage problem

I’m struggling on this issue once the addpage method is called on the pageview … the page is added at the end of the content while the content is in horizontal orientation and the direction of moving is from right to left ,
the page is added at the end of the left direction

which makes the pageview approaches to the end of the content while it must be generating new page on each move and added to the end of the content on the right side ,

how can we add a new page so that it can be on the same order of the content ?
