Creating a transition when changing properties in angular 2/4

I want to create a transition effect whenever I change the value of a property.

I tried doing the following

    @Component({   
    selector: 'image-holder',
    template: `
        <div class="carousel-image">
            <img src="{{ image }}" [@slideInRight]="slide" />
            <span>{{ text }}</span>
        </div>
    `,
    styleUrls: ['../greenscreen.scss'],
    animations: [
        trigger(
            'slideInRight',
            [
                transition(
                ':enter', [
                style({transform: 'translateX(100%)', opacity: 0}),
                animate('500ms', style({transform: 'translateX(0)', opacity: 1}))
                ]
            ),
            transition(
                ':leave', [
                style({transform: 'translateX(0)', 'opacity': 1}),
                animate('500ms', style({transform: 'translateX(100%)',opacity: 0}))
                ]
            )
            ])
    ]
})
export class ImageHolderComponent implements OnChanges {
    @Input()
        image: string;
    @Input()
        text: string;

    public slide: boolean = true;

    public ngOnChanges(changes: { [propKey: string]: SimpleChange }){
        this.slide = !this.slide;
    }
}

What I assumed was changing the property would trigger the component to start the animation effect again but that doesn't work as expected
