Displaying twitter feeds using javascript

Hi

I want to display twitter data of the users in twitter format. I have an api which returns twitter html's. I make an ajax call in javascript to the api and get the HTML data. But when i set the div innerHTML to the html data it does not display in twitter format. It displays in raw format. If have the same data written in the html directly under the div it displays in  twitter format. I am attaching two files stream_old.html and test.html. In test.html i have copied that html data and it displays in twitter format.

In case of stream_old.html, i have made and ajax call and get the data and then set in the div, but it does not displays in twitter format. In both the files i have included the script <script async src="http://platform.twitter.com/widgets.js" charset="utf-8"></script>

stream_old.html hits an api https://stream.alphamaven.com/markets/lse/indices/ftse_100/cashtag_stream/oembed?uid=825060248, this is a continous stream of data. I have another API which returns fixed 3 tweets, even in that it is not displayed in twitter format.

Also attaching the a.js file required for stream_old.html


thanks
