title: Need to Refresh Child component on Toggle Button Angular5 and Typescript
body: <p>I have this scenario where I am doing translations using toggle button on different modules. The Problem is the code for toggle is written in app.component.ts and I however tried to get the language value in child components but the functionality is only working on page refresh and not on standalone.</p>
  
  <p>Meaning, when i come to  home page and switch toggle from En to Fr, it doesnot work but when i goto another link in navigation, the translation works. In short, i need to refresh my child component UI whenever user changes the toggle in parent component.</p>
