Actually indexing content in Ajax gives a lot 'headache', after many months researching I found some ways, I’m still in the process of testing, but, I’m already seeing good results... you may be doing the following:
Google provides some tools that do content indexing in Ajax/ javascript/ Angular SEO etc.. I did this process and the url’s, titles and descriptions appeared in the search engine/google searches.

Add a website, then go to rastreamento > Buscar como o Google and insert the pages you want to render and then index. There are many other excellent tools on this site for us to assist, it is worth studying them.

After Seo4ajax captures the pages of your site, you can donwload the sitemap, send it to the file manager, where you host your site, and add it to the Google Webmasters Tools, this helps as well.
Any doubt may be asking, if I know I’ll be helping, thanks!
