Title: Remove replacing apostrophes with double apostrophes before trying to parse string to JSON

For example let's have JSON

{"test" : "it's perfectly valid JSON"}

And then you plug this JSON to your element's published property attribute, the parsing will fail due to replace which is being done right now.

I think it's reasonable to remove this replace and allow only proper JSON to be parsed.
