Angular 2 - change videos src after clicking on di

Question

I have problem with video src. After clicking on my div (camera) in source code I can see that video src is changing properly, but videos arent being played. What should I do?

Below are my components - streaming.component.ts (responsible for displaying videos of chosen camera component) and camera.component.ts (for viewing icon with camera name)

streaming.component.ts

import {Component} from '@angular/core';
import {CameraComponent} from '../camera/camera.component';

@Component({
   moduleId: module.id,
   selector: 'streaming',
   template: `
            <camera cameraName="Kamera 1" (click)='cameraStream("sample.mp4")'></camera>
            <camera cameraName="Kamera 2" (click)='cameraStream("sample2.mp4")'></camera>
            <camera cameraName="Kamera 3" (click)='cameraStream("sample3.mp4")'></camera>
            <camera cameraName="Kamera 4" (click)='cameraStream("sample4.mp4")'></camera>
            <video width="800" controls>
                <source src = "{{cameraSrc}}" type="video/mp4">
                Your browser does not support HTML5 video.
            </video>
            <p>{{cameraSrc}}</p>
            `,
directives: [CameraComponent]
})
export class StreamingComponent {

 cameraSrc:string;
 constructor() { }

 cameraStream(chosenCamera :string){
    this.cameraSrc=chosenCamera;
  }
 }

Videos are working ,because when I put

<source src = "{{cameraSrc}}" type="video/mp4">

everything is fine.

camera.component.ts

import { Component ,Input } from '@angular/core';

@Component({
    moduleId: module.id,
    selector: 'camera',
    templateUrl: 'camera.component.html'
})
export class CameraComponent {
     @Input() cameraName:string = "";

     constructor() { }

 }

Here is what I get after clicking on camera2 for example .

I cant comment because I am too new, sorry.

The reason that interpolation isnt working for you is because its used for data binding , not property binding. The brackets indicate that its a property of the element and not an observable attached to a static property.
