How to translate search box placeholder text?

Hi,
I want to translate the search box placeholder value but it is in javascript file. I was able to translate other fileds as they are compatible for i18n but searchbox not. The code in javascript is as follows
(geoposition.js line 36):
`$searchInput = $('<input>', {'type': 'search', 'placeholder': 'Start typing an address …'}),`
any idea?
