Thanks @Lilly. Actually, I want to display some data from third party API for each topic and for that I am looking for a way to call the third party api when data load on list page.
So, when the page loads I should be calling the api and then I want to render data. At the moment I am gethering all the list data and calling third party api whatever data comes I just append that data in DOM. But I want to fetch data on lazy load of topic list page.
