user_validation function is not invoked in Home controller in codeigniter - php

Question

I need to validate a user form, which I am trying to submit after taking the input in view named as 'home.php', where I have specified the base_url('Home/user_validation').
With Home is name of the controller and user_validation is the method name. I tried to figure out the issue but I could not understand why not any other function is being invoked apart from index function in Home controller. Please help me in this case.
Controller Home.php
public function user_validation()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required');
$this->form_validation->set_rules('password', 'Password', 'trim|required');
if ($this->form_validation->run() == FALSE) {
$this->session->set_flashdata('message', 'Invalid username and password.');
redirect('home');
}
else {
$user_name123 = $this->input->post('username');
$teacher = $this->input->post('remember');
if ($user_name123 == 'admin') {
$query = $this->login_model->validate();
echo("Logged in");
}
}
}
Model login_model.php
function validate()
{
$this->db->where('admin_username', $this->input->post('username'));
$this->db->where('admin_password', $this->input->post('password'));
$this->db->where('active_status', 'Yes');
$query = $this->db->get('cis_tbl_admin');
if ($query->num_rows() == 1) {
return true;
}
else {
return false;
}
}
View home.php
<form action="<?php echo base_url('Home/user_validation') ?>" method="post" id="instantform">
<fieldset>
<div class="input-prepend" title="Username" data-rel="tooltip">
<span class="add-on"><i class="icon-user"></i></span>
<input autofocus class="input-large span10"

</div>

<br/><br/>
<!--<a class="ajax-link" href="<?php echo base_url(); ?>parent_info/get_students_info"> <span class="hidden-tablet">Parent Login</span></a>-->
</p>

<input type="hidden" name="sys_date" id="sys_date" value="<?php echo $sys_date; ?>">
<input type="hidden" name="sys_time" id="sys_time" value="<?php echo $sys_time; ?>">
<input type="hidden" name="details" id="details" value="<?php echo $details; ?>">
</form>

Check your config routes file to be sure you call functions of the home controller:
$route['Home/(:any)'] = 'Home/$1';
