title: SSRM refresh the master detail cell after applyServerSideTransaction
body: <p>According the document: <a href="https://www.ag-grid.com/angular-data-grid/master-detail-refresh/" rel="nofollow noreferrer">https://www.ag-grid.com/angular-data-grid/master-detail-refresh/</a>
  we can refresh the detail row by applying transaction</p>
  <p>In my case, I tried to apply a serverSideTransaction on the grid,
  I can see the cell value change after applying transaction,
  but the detail grid of that row remains the same</p>
  <p>Does this document also work for server side row model - applyServerSideTransaction() method?
  or it only works with using normal applyTransaction() method..?</p>
