I need to have only signature => {"config":"wireless","section":"radio0","values":"{"disabled":0"}

Can anyone help me? I try to convert to String this object and split doing

var aux = signature.split('\\').join('');
var jsonObject = JSON.parse(aux);

But i get the same result {"config":"wireless","section":"radio0","values":"{\"disabled\":0"}

My last post: Split string by "\" Node.js
