Hi Anil,
Did you define "callMyFunction" on the ngb-tab-title components controller? If not, the click is probably handled by the ngb tabs system. you can add your own clickhandler inside a ngbTabTitle template like this: <ngb-tabset> <template ngbTabTitle> <span (click)="callMyFunction()">Profile </span></template> <ngb-tabset> As documented in the excellent ngBootstrap documentation!
