I have created a header component in my Angular project and want to pass the `{{title}}` property from my main app component into my header component so that the title of the app is alway visible inside the header component.

I added `@Input() title: string;` to the header component with the Input import in the core, then call the property `{{title}}` in the header html but it's blank. so I guess I'm missing something but not sure what?
