Codeigniter not updating my data - php

Question

So I'm new to codeigniter and developing a viewing catalogue website. And so far my update function isn't working and I've been at this for 3 hours
so here's my view:
<?php echo validation_errors(); ?>
<?php echo form_open('catalogPages/updateEvent'); ?>
<input type="hidden" name="id" value="<?php echo $events['event_id']; ?>">
<div class="form-group">
<label>Title</label>
<input type="text" class="form-control" name="title" placeholder="Add
Title" value= "<?php echo $events['event_name']; ?>">
</div>
<div class="form-group">
<label>Body</label>
<textarea id="editor1" class="form-control" name="body" placeholder="Add
Body" value = "<?php echo $events['event_desc']; ?>"></textarea>
</div>
<button type="submit" class="btn btn-default">Submit</button>
My Model:
public function editEvent()
{
$data = array(
'event_name' => $this->input->post('event_name'),
'event_desc' => $this->input->post('event_desc'),
'event_id' => $this->input->post('event_id')
);
$this->db->where('event_id', $this->input->post('event_id'));
return $this->db->update('events', $data);
}
Controller:
public function editEvent($id = NULL)
{
$this->load->model('event_model');
$data['events'] = $this->event_model->get_event($id);
$this->load->view('adminEventUpdate', $data);
}
public function updateEvent()
{
$this->load->model('event_model');
//$id = $this->input->posts('event_id');
$this->event_model->editEvent();
}
It works but so far when I try to update the data doesn't seem to be updated but rather doesn't change at all.

When this Html form is submitted, the $_POST array has the keys:
'id', 'title', and 'body'.
There are no inputs named 'event_id', 'event_name', 'event_desc'.
The Html input properties 'name' need to change.
