How to Handle Pager Change Event

Hello,

I have a server side application which has pager implemented. Using ng2-smart-table, on my service, I am extending ServerDatasource and setting .setPaging(1,100) and then loading data onto UI. But how can I call an API to server to load the next chunk of data?

Is there any pager event which can be used to update the API page and size? Any suggestion or hint will be helpful.

Thanks,
Sovan
