name attribute stripping out underscores

  _helpers.safename = function(str) {

  };

safename helper is stripping out the underscores from my name attributes. first_name becomes firstname. the replaceing regex simply needs to account for the _, which it currently doesn't

Please replace safename function with following code .
return e.replace(/\s/g, "-").replace(/[^a-zA-Z0-9\_-]/g, "").toLowerCase()
