Subgrid/view Pagination not working for Virtual Entity

Hello All,

I am facing one concern in MS Dynamics CRM where we are using one Virtual Entity and showing its data as a subgrid in Account Entity.

Problem is, we have set per page record limit to 20 in the grid(which cannot be changed or increased). If we get the data of more than 20 records, remaining records move to next page. 

But however, we are not able to move to next page in this subgrid. Any idea to resolve this would be very helpful. Neither the sorting and filter works.
