Real-time data - Sorting does not keep when the new data comes in

I have been using jQuery Datatable in the past. This package works really great until we decide to build the website with Angular 4. I have tried angular-datatable but they haven't ported many features like reloadData() or _fnAddData() to Angular package yet which is why I had to find alternative solution and found ng2-smart-table.

Smart table looks great with real-time data. The only issue is, if I have sorted by email address or full name, it reverted back to unordered list when the new data is updated.
