Dynamic Propery Bindning - angular2

Question

   **how can we dynamically bind the property of child component to the html page of parent component in angular2?**

  **Component property binding 

父组件应该能够动态访问html页面中的子组件**属性     Parentcomponent.ts         为父级{     ngOnInit（）{

    call child component method
   } }
**Here the value must be binded**
    parentcomponent.html
    "here how to bind items of childcomponent through parentcomponent "
    ex: i want the value like {{items.name}}
    and it has to change dynamically when value in childcomponent changes
    **This is child component whixh will get the value of the** item.name  from service and bind it to the html of parent component
    childcomponent.ts
    ChildComponent{
    items:any;(Item is json object with properties item id,item name etc)
    ngOnInit(){
    this.items=Itemsservice.getItems();
    }
    }
     **This is the service method.**
    itemservice.ts
    @Injectable()
    export class ItemService{
    getItems(){
    return items;
    }
