Getting 404 trying http PUT using Node Express Postgresql

Edit: NEVERMIND - I made a small mistake in the Angular service. My bad.

I'm trying to teach myself more backend by building a simple CMS using angular, Node and Express, and PostgreSql. I figured out how to do achieve all the CRUD functionality except UPDATE. I thought I understood what to do but I can't figure out where I'm going wrong. I keep getting a 404. What am I misunderstanding or going about the wrong way? I know this is simple but I'm pretty new so any help in understanding where I'm getting confused is really appreciated. Here's the relevant code:

HTML

<form ng-submit="updateBlogEntry(specificBlog.id, specificBlog.title, specificBlog.author, specificBlog.imageurl, specificBlog.content)">
    <h2>Title:</h2>
        <input type="text" ng-model="specificBlog.title"></input>
      <br>
    <h3>Author:</h3>
        <input type="text" ng-model="specificBlog.author"></input>
      <br>
    <h3>Photo:</h3>
        <input type="text" ng-model="specificBlog.imageurl"></input>
      <br>
    <h3>Content:</h3>
      <textarea type="text" rows="5" cols="50" ng-model="specificBlog.content">
      </textarea>
      <br>
    <button type="submit">Save Changes</button>
  </form>

Angular Controller

  var id = $stateParams.id;
  var title = $stateParams.title;
  var author = $stateParams.author;
  var imageurl = $stateParams.imageurl;
  var content = $stateParams.content;

  $scope.updateBlogEntry = function(id, title, author, imageurl, content) {
    adminService.updateBlogEntry(id, title, author, imageurl, content);
  }

Angular Service

this.updateBlogEntry = function(id, title, author, imageurl, content) {
    return $http({
      method: 'PUT',
      url: 'updateBlogEntry/' + id,
      data: {
        id: id,
        title: title,
        author: author,
        imageurl: imageurl,
        content: content
      }
    })
    .success(function(data) {
      alert("Entry Updated");
    })
    .error(function(data) {
      alert("Error Updating"); 
    })

app.put('/api/updateBlogEntry/:id', blogCtrl.updateBlogEntry);

// CONNECTIONS //
var port = config.PORT;
app.listen(port, function() {
    console.log('Listening on port ' + port);
});

Node Controller

updateBlogEntry: function(req, res, next){
        db.blogs.blog_update([
            req.params.id,
            req.body.title,
            req.body.author,
            req.body.imageurl,
            req.body.content
        ],
        function(err, results){
            if (err){
                console.error(err);
                res.send(err);
            } else {
                res.send(results[0]);
            }
        })
    }

blog_update.sql

UPDATE blogs

  title     = COALESCE($2, title),
  author    = COALESCE($3, author),
  imageurl  = COALESCE($4, imageurl),
  content   = COALESCE($5, content)
WHERE id = $1

RETURNING * ;

The error in the console:
