When you create a custom Display Template and you deploy it, you can see the HTML uploaded, but you can’t see its JS (created automatically in theory).
You don't have the correspondent JS of your HTML Display Template
1. Access to your Site with SharePoint Designer 2. Go To: All Files -> _catalogs -> masterpage -> Display Templates -> Content Web Parts 3. Check out and open your HTML and edit some part (Add a space, for example). 4. Close the file, check it in and publish a major version.
Now you should see the JS created.
