visual studio 2017 goto method in file - visual-studio

Question

I am trying to use VS 2017 on my typescript project. I am using the goto member and trying to navigate to methods in my current file. However, VS 2017 does not seem to filter the methods properly. In the goto I am using "m and currentfile" and for example, if I try to filter "extractData", it does not seem to filter properly.
My .ts file is as follows.
export class FooterLinksServiceSiteCore implements FooterLinksService {
/**
*
* #param {Http} private http [description]
*/
constructor(private http: Http) {
}
/**
* [LoadFooterLinks description]
* #return {Observable<FooterLink[]>} [description]
*/
get(footerValuesLink: string): Observable<FooterLink[]> {
}
/**
* [extractData description]
* #param {Response} res [description]
*/
private extractData(res: Response): Array<FooterLink> {
let mappedFooterLinks: Array<FooterLink> = new Array<FooterLink>();
let footerLinks = res.json();
footerLinks.forEach(footerLink => {
mappedFooterLinks.push(new FooterLink(footerLink.Title, footerLink.Url));
});
return mappedFooterLinks;
}
/**
* [handleError description]
* #param {Response | any} error [description]
*/
private handleError(error: Response | any) {
// In a real world app, we might use a remote logging infrastructure
let errMsg: string;
if (error instanceof Response) {
const body = error.json() || '';
const err = body.error || JSON.stringify(body);
errMsg = `${error.status} - ${error.statusText || ''} ${err}`;
} else {
errMsg = error.message ? error.message : error.toString();
}
console.error(errMsg);
return Observable.throw(errMsg);
}
}
