@diaconescu-stefanandrei,
It seems to be working fine, please take a look at this Stackblitz for working code.
If you are still facing issue, kindly create a sample project reproducing the issue and share it with us over Google-Drive or Onedrive (or update the code in shared Stackblitz, fork it and share with us) so that we can look into the code, understand the scenario better and help you out.
