How to capture SignalR Response on Angular 6 - angular6

Question

I am struggling to listen to the message I am getting from a .net application using signalR on angular 6 application.
In angular.json file I have added /node_modules/signalr/jquery.signalR.min.js & jquery
Package.json includes
"dependencies": {
"#angular/animations": "^6.0.0",
"#angular/cdk": "^6.3.1",
"#angular/common": "^6.0.0",

"signalr": "^2.4.1",
"uuid": "^3.1.0",
"web-animations-js": "^2.2.5",
"zone.js": "^0.8.20"
}
Service file:
import { Injectable } from '#angular/core';
declare var $: any;
#Injectable({
providedIn: 'root'
})
export class SignalRServiceService {
private connection: any;
private proxy: any;
private url = 'https://localhost:8090';
constructor() {}
public startConnection(): void {
this.connection = $.hubConnection(this.url);
this.proxy = this.connection.createHubProxy('testhub');
// connection starts
this.connection.start().done((data: any) => {
console.log('Connected to Hub');
}).catch((error: any) => {
console.log('Hub error -> ' + error);
});
this.connection.proxies.testHub.on('databaseUpdateNotification', () => {
console.log('captured response');
});
}
}
I am able to see the 'Connected to Hub' message in console. I believe there is no connection issue. When .net some message broadcaster broadcasting I am not able to capture the response.
How to capture the response here?
Appreciate all your help....
Thanks a ton

On your method change to:
this.connection.proxies.testHub.on('databaseUpdateNotification', (data) => {
console.log(data);
});
