Extracting filters in html

[jgerstle]

In HTML there is a placeholder attribute which we use for a bunch of our inputs. Which would look something like this <input placeholder="phone"> I would like to translate the text in the placeholder. I could theoretically do this using filters like so: <input placeholder="{{'phone'|translate}}">. However, when running the grunt extract task I created, the text does not get added to the pot file. Am I missing something or do I just have to add it as a variable in js and pass it to the front end which I'd rather not do.
