Angular Form Submit Post to Database

Question

I am trying to post my form data to my database. When I click the submit button nothing happens. It should be calling my addDiscovery method in the discoverCtrl, but it just does nothing. I am getting no errors and have watched several tutorials in which (to me) I don't see the difference in my code and what is presented. Please tell this Angular noob what he is doing wrong!...Thanks in advance.

discoverCtrl.js:

angular.module('app')
.controller('discoverCtrl', ['$scope', '$http', function($scope, $http, $log) {
    $scope.title = "Discover It!";

    $scope.objects = ['animal', 'art', 'food', 'landform', 'object', 'plant', 'pokemon', 'vehicle'];

    this.discovery = {};

    $scope.addDiscovery = function() {
        this.discovery.image = "";
        this.discovery.location = ""/*gps api call*/;
        this.discovery.discoveredOn = Date.now();
        console.log("I'm posting something maybe?");
        $http.post('/discover', {discovery: this.discovery}).success(function(data) {

        });
        this.discovery = {};
    };
}]);

discover.html:

<h1>{{title}}</h1>

<form name="discoverForm" ng-controller="discoverCtrl" ng-submit="discoverForm.$valid && discoverCtrl.addDiscovery" novalidate>

<input ng-model="discoverCtrl.discovery.name" type="text" class="form-control" placeholder="What is the name of your discovery?" title="name" required />

<select ng-model="discoverCtrl.discovery.objectType" class="form-control" ng-options="object for object in objects" title="objectType" required>
    <option value="" disabled selected>Select what type of discovery you have found.</option>
</select>

<textarea ng-model="discoverCtrl.discovery.description" class="form-control" placeholder="What does your discovery look/feel/smell like? Are there any other observations or knowledge you can share about it?" title="description" required></textarea>

<!--location found by gps TODO-->

<div>Discovery is {{discoverForm.$valid}}</div>
<input type="submit" ng-click="discoverCtrl.addDiscovery" class="btn btn-primary pull-right" value="Discover It!" />

</form>

server.js (sorry for the length. The route is at the bottom, but I didn't know if it could have been something else in here as well so I wanted to include it.):

// requires express and body-parser
var express = require('express');
var bodyParser = require('body-parser');

var GoogleStrategy = require('passport-google-oauth20').Strategy;
var configAuth = require('./auth');

// OAuth 2.0-based strategies require a `verify` function which receives the
// credential (`accessToken`) for accessing the Facebook API on the user's
// behalf, along with the user's profile.  The function must invoke `cb`
// with a user object, which will be set at `req.user` in route handlers after
// authentication.
passport.use(new GoogleStrategy(configAuth.googleAuth,
  function(accessToken, refreshToken, profile, cb) {
    console.log('access token is', accessToken)

    return cb(null, profile);
  }));

// Configure Passport authenticated session persistence.
//
// In order to restore authentication state across HTTP requests, Passport needs
// to serialize users into and deserialize users out of the session.  In a
// production-quality application, this would typically be as simple as
// supplying the user ID when serializing, and querying the user record by ID
// from the database when deserializing.  
passport.serializeUser(function(user, cb) {
  cb(null, user);
});

passport.deserializeUser(function(obj, cb) {
  cb(null, obj);
});

//requiring and setting up mongo database/collections
var mongojs = require('mongojs');

var collections = ["users", "discoveries"];

// creates a databse in mongo called scrape with two collections: articles and comments
var db = mongojs('discoverIt', ['users', 'discoveries']);

// lets us know if there is an error with the database if it doesn't turn on
db.on('error', function(err) {
    console.log('Database Error: ', err);
});

正如@dustmouse所说，我需要（）... oops！
