Is there a way to get data from server while exporting to CSV?

Hey,

I was going through http://allenfang.github.io/react-bootstrap-table/example.html#remote "Remote Exporting CSV" example and was wondering if there is a way to get data from the server in "onExportToCSV" method?
The example shows a synchronous function which expects all the data to be present in the state before callling onExportToCSV. What if I don't want to load all the data ahead of time but want to get the data only when 'export to CSV' is clicked?

Any help is appreciated.
