Node update not working, format is wrong while send to api - node.js

Question

I try to update my data from Angular to Node.js
component.ts
updatefunction(id,data){
console.log("component",data);
//component {role: "User", _id: "5c2dc052d6bfba36b41b34dd", name: "Test", email: "test123#gmail.com", //username: "Test"}
this.uAdminService
.updateUser(id,data).subscribe(
result => {
//console.log(result.json());
},
error => {
console.log(error.json());
}
);
}
in myservice.ts
updatefunction(id, data){
console.log("service", data);
//service {role: "User", _id: "5c2dc052d6bfba36b41b34dd", name: "Test", email: "test123#gmail.com", //username: "Test"}
let headers = new Headers({ 'x-access-token': this.token, 'Content-Type': 'application/x-www-form-urlencoded' });
let options = new RequestOptions({ headers: headers });
return this.http.put(this.url+id, data, options);
}
my nodejs controller
router.put('/:id', VerifyToken, function (req, res) {
console.log(req.body);
//{'{\n "role": "User", \n "_id": "5c2dc052d6bfba36b41b34dd" \n}'}
User.findByIdAndUpdate({_id:req.params.id}, req.body, {new: true}).select("-password")
.then(users => {
res.send(users);
}).catch(err => {
res.status(500).send({
message: err.message || "Some error occurred while retrieving Report."
});
});
});
my req.body console like this {'{\n "role": "User", \n "_id": "5c2dc052d6bfba36b41b34dd" \n}'} but i pass from angularjs in this format {role: "User", _id: "5c2dc052d6bfba36b41b34dd", name: "Test", email: "test123#gmail.com", //username: "Test"}
I don't know why it's converting so that it's not update to db
if i console from api it will like this { name: "Test",email: "test123#gmail.com"}

Update myservice.ts like below:
updatefunction(id, data){
console.log("service", data);
//service {role: "User", _id: "5c2dc052d6bfba36b41b34dd", name: "Test", email: "test123#gmail.com", //username: "Test"}
let headers = new Headers({ 'x-access-token': this.token, 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
return this.http.put(this.url+id, data, options);
}
Changed the Content-Type to application/json as you are sending a json formatted data and not form data.
