Thank you for your answer!
Yep it was a late a bit 
I already solved the problem with āFaking pagesā. I also contacted with axure support, and they write this message back to me: (i copy this here because it can be useful to somebody who have similar problem)
Thanks for reaching out! Repeaters in Axure RP do not have global datasets, so itās a bit tricky to control adding and deleting rows in a repeater when the repeater is on a different page than the button controls. The easiest solution that we would recommend would be to have the repeater and button controls all on the same page, and to simulate different pages by putting each "page" into different states of a single dynamic panel. This would allow your "Add" and "Delete" buttons to target the repeater directly while still simulating changing pages.
That said, some of our forum power users have come up with clever ways to simulate the repeater being accessible on different pages by leveraging global variables and some advanced logic. Below is an example built by one of our power users that allows you to add and remove entries to a list via controls on another page. Theyāve included a good explanation of the setup as well:
Another way that people have passed multiple data values from one page into a repeater onto a different page is with a single global variable, separating text with symbols such as "$". This take a bit more leveraging of string functions in Axure RP but uses fewer variables than the first approach to get a similar result. Hereās a link to an example file where you can take a look at the logic to see if youād prefer this method:
Hopefully one of these options helps!
