Change page after init with remote ajax data

alex916

I'm using DataTables 1.10.12 configured with external ajax data and "serverSide" : true.
It's work great but i have to get a parameter from the URl and set DataTables initial page.
I tried adding:
$('.datatable').DataTable().page(${pageNumber}).draw(false);
to init.dt event.
Datatable paging is correctly selected but remote data isn't updated and always show first page data.
Also adding an ajax.reload not solve the problem.
Probably i'm using a wrong event because if i execute:
$('.datatable').DataTable().page(${pageNumber}).draw(false);
from Chrome debug console after page is loaded, it works as expected.

Thanks in advance for help.
