Can't update user model in express? - node.js

Question

I'm trying to do a put request to update a user model but instead my router just sends another get request.
Here's my router
router.get('/update', isLoggedIn, function(req, res) {
res.render('update.ejs', {
user : req.user // get the user out of session and pass to template
});
});
router.put('/update', function(req, res) {
var username = req.body.username;
var profile_type = req.body.prof_type;
var pic = req.body.profile_pic;
var aboutme = req.body.whoami;
console.log(req.body.whoami);
User.findById(req.params.id,function(err, userup){
if (!userup)
return next(new Error("Couldn't load user"));
else {
userup.username = username;
userup.prof_type = profile_type;
userup.profile_pic = pic;
userup.whoami = aboutme;
userup.save(function(err) {
if (err)
console.log('error on update');
else
console.log('successful update');
});
}
});
res.redirect('/profile');
});
Here's my html input form
<form action="/update" method="put">
<div class="form-group">
<label>Username</label>
<input type="text" class="form-control" name="username">
</div>
<div class="form-group">
<h2> Pick a type of profile</h2>
<input type="radio" class="form-control" name="prof_type" value="true">Tutor<br>
<input type="radio" class="form-control" name="prof_type" value="false">Student
</div>
<div class="form-group">
<label>Link to profile picture</label>
<input type="text" class="form-control" name="profilepic">
</div>
<div class="form-group">
<label>About me</label>
<textarea name="whoami" class="form-control">Enter text here </textarea>
</div>
<button type="submit" class="btn btn-warning btn-lg">Update</button>
</form>
I've also tried changing them to be /update/:username, however, after I click the update button with the fields, I GET this address
http://localhost:3000/update?username=bob&prof_type=false&profilepic=bob&whoami=bob
Not sure why I'm not updating the model or even why it's not putting. Any help is much appreciated, thanks!

HTML only supports GET and POST requests. See the specification for details:
The method and formmethod content attributes are enumerated attributes
with the following keywords and states:
The keyword get, mapping to the state GET, indicating the HTTP GET
method. The keyword post, mapping to the state POST, indicating the
HTTP POST method. The invalid value default for these attributes is
the GET state. The missing value default for the method attribute is
also the GET state. (There is no missing value default for the
formmethod attribute.)
You can use the PUT method only with an ajax request. For example in jQuery:
$.ajax({
url: '/update',
type: 'PUT',
success: function(result) {
// Do something with the result
}
});
