typeahead performance issue

[fdu-axiometrics]

typeahead setup

<input type="text" class="form-control" placeholder="Search for..." [typeahead]="getAsyncData(getContext())"(typeaheadOnSelect)="typeaheadOnSelect($event)" [(ngModel)]="searchTerm">

private getContext():any {
        return this;
    }

private getAsyncData(context:any):Function {

      return function ():Promise<Object[]> {
                return context.searchService.searchCompaniesByName(context.addCompaniesModalSearchTerm.trim()).toPromise();
            };
}

getAsyncData function would be constantly called as long as the page is open and no user interaction is on the page.

This should be fixed with the new Observable implementation #584 .
