Using the Express.js app.post request is not working

I am having an issue with the Express.js library.

If I specifically add app.post it does not work but if I use GET or app.all it works just fine with my post data.

Could some one take a look at my code and see what i could be doing wrong? Also just for a further clarification i will be splitting all this up later on i just have the data base connection and every thing else in one file to test things.

var express = require('express');
var app = express();
app.set('view engine', 'ejs');
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));


var server = app.listen(3000, function () {
    var host = server.address().address;
    var port = server.address().port;

    console.log('Example app listening at http://%s:%s', host, port);
});

var getuser_Information;

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/data/db/');
var db = mongoose.connection;

db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function (callback) {
    // yay!
});
//testing the mogno db for createing a new table schema for a user login using the mognose api example
var UserSchema = mongoose.Schema({
    name:String
});


var usersinfo = mongoose.model('Userinformation', UserSchema);
//sets up the log in


app.post('/',function(req, res) {
    getuser_Information = new usersinfo({ name:req.body.usernames});
    getuser_Information.save(function (err,getuser_Information) {
        if (err) return console.error(err);
        console.log(silence);
    });
    res.render('def',{
        firstnames:getuser_Information
    });
});

So i was not routing the correct information and figured out the diffrences of when using app.all. here is the code that i have now.

var express = require('express');
var app = express();
app.set('view engine', 'ejs');
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));


var server = app.listen(3000, function () {
    var host = server.address().address;
    var port = server.address().port;

    console.log('Example app listening at http://%s:%s', host, port);
});

var getuser_Information;

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/data/db/');
var db = mongoose.connection;

db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function (callback) {
    // yay!
});
//testing the mogno db for createing a new table schema for a user login using the mognose api example
var UserSchema = mongoose.Schema({
    name:String
});


var usersinfo = mongoose.model('Userinformation', UserSchema);
//sets up the log in

app.get('/',function(req, res) {
    res.render('def',{
        firstnames:""
    });
});
app.post('/run',function(req, res) {
    getuser_Information = new usersinfo({ name:req.body.usernames});
    getuser_Information.save(function (err,getuser_Information) {
        if (err) return console.error(err);
        else
            res.render('def',{
                firstnames:getuser_Information
            });
    });


});

process.on('uncaughtException', function (err) {
    console.log("\n\r *Uncaught Exception event* \n\r")
    console.log(err);
});
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <button type="submit" class="btn btn-default">Submit</button>
</form>


<h1>Hello <%= firstnames %></h1>

app.post('/',function(req, res) {
    getuser_Information = new usersinfo({ name:req.body.usernames});
    getuser_Information.save(function (err,getuser_Information) {
        if (err) return console.error(err);
        else
          res.render('def',{
             firstnames:getuser_Information
          });
    });
});

Node.js is asynchronous.
