I have created a library that takes input variable type as a string.

<my-lib [query] ="query"></my-lib>


export class Query {
  elQuery: string=""

In my-lib I have an input box that takes query as ngModel whenever I update query in-app it gets reflected to my-lib. But whenever I update the query in the library it won't update back. Can anyone tell me how I can update value of query in app?
