JSONP broken

[svbatalov]

Hello.

I query OSM Nominatim API via JSONP callback. Few months ago it stopped working -- whenever I try to search something, the following error is thrown:

Uncaught TypeError: L.Control.Search.callJsonp is not a function

After some investigation it turns out that recent versions call _retrieveData directly instead of using this._retrieveData.call(...), as it was before. So instead of 2 arguments (inputText and callback) the function is called with three, so inputText = this and callback = inputText.

Created PR #322 that should fix this.

So, hacking around a bit with this code and the PR this last day or two. The PR does stop the error, but the search results produce an "undefined" result in the search box. I've tested this by changing the source code on the example online as well as my personal project.

If it's any help, this is the request URL: https://nominatim.openstreetmap.org/search?format=json&q=London&json_callback=L.Control.Search.callJsonp

And this is the response:
