Will Search Engines grab javascript generated keyword and description meta tags?
===

I have a website that loads its template via ajax.
The `description` and `keywords` meta tags are present on this `template.html` file and not on the current `index.html` page being loaded. After the template is loaded it will embed the meta tags from the template into `index.html` file.

Will Google or any other search engine be able to read this page's `description` and `keywords` meta tags which were dynamically inserted?

I'm asking this because I've heard that many search engines don't support javascript, although, when getting a preview screenshot from the website search result on google it displays the page containing the whole layout (after the insertion of `template.html`) so this made me a but curious.

Thanks in advance
