This issue is caused by a missing import of PrimeNG's ButtonModule.

Please add this import to the same module, your component is defined in.

import {ButtonModule} from 'primeng/primeng';

...

@NgModule({
   imports: [
      ...
      ButtonModule
   ]
   ...

In the form i have a primeng text area and forgot to add name attribute to the text area. Primeng buttons were not displaying because of this. I corrected this mistake and everything works fine.
