Express + Angular update route: Error: Cannot PUT - angularjs

Question

I'm trying to update a schema using form, however, both on app.put and app.post (which I've seen as a possible solution) i get
PUT https://myapp-demo.herokuapp.com/api/events/5523da4d97c5000300f6e713 404 (Not Found)
and error from ajax callback
Error: Cannot PUT /api/events/5523da4d97c5000300f6e713
on clientside, I make this request:
$scope.saveEvent = function(id) {
$http.put('../api/events/' + id, $scope.formData)
.success(function (data) {
$scope.events = data;
})
.error(function(data) {
console.log('Error: ' + data);
})
};
In express routes, I do this:
app.put('../api/events/:id', function (req, res){
var user = req.user;
var id = req.params.id;
var update = {
$set: {
title: req.body.title,
description: req.body.description,
}
};
Event.findByIdAndUpdate(id, update, function (err, event) {
if(!event) {
res.statusCode = 404;
return res.send({ error: 'Not found' });
}
console.log("event updated");
Event.find(function(err, events) {
if (err){
res.send(err)
};
res.json(events);
});
});
});
I tried to pass event._id differently, by using req.params.id and passing id with form like req.body.id, it all leads to the same result. I've also read about creating hidden input for helping method-override to override form methods. However, having this didn't help.
<input type="hidden" name="_method" value="put">
<md-button class="md-raised md-primary" ng-click="saveEvent(eventId)">Save</md-button>
UPDATE
Indeed, the initial proble was in my put route. I've found a new problem now. When I try to update it again, I get
Error: Object {error: "Not found"}
It happens even after I refresh page or restart server.

The following is invalid:
app.put('../api/events/:id'...
It needs to be in reference to the namespace, or in your case the root:
app.put('/api/events/:id'...
