We can trigger change event whenever Slider value is changed.
 In other term, this event will be triggered while drag the slider thumb.
```html
 <ejs-slider id='default' [value]='value' [step]="step"></ejs-slider>
import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: `<ejs-slider id='ticks_slider'#slider [value]='value' [min]='min' [max]='max' [type]='type' [step]='step' [ticks]='ticks' (change)='change($event)' ></ejs-slider>
    </div>
    Change event:
    <div id="slider"> 
    </div>`,
    styleUrls:['index.css'],
})
export class AppComponent {
    public value: number = 30;
    public min: number = 0;
    public max: number = 100;
    public step: number = 5;
    public type: string = 'MinRange';
    public ticks: Object = { placement: 'Before', largeStep: 20 };
    private change(args: ChangeEventArgs) {
    if(args.value) {
        document.getElementById("slider").innerHTML = JSON.stringify(args);
      }
