Can you check my pagination?[SOLVED]

Hello here is my issue, mi pagination has the url working fine, and I can see the pagination class insisde m view, but I still do not know how to retrieve just the number of entries that I want:

Here is my controller(News, function blog):

PHP Code:

       public function blog() {
                $data['blog'] = $this->blog_model->get_blog();
                $data['categorias'] = $this->categorias_model->get_categorias();
                $data['title'] = 'Blog';
        
        
                $config = array();
                $config["base_url"] = base_url() . "blog";
                $config["total_rows"] = $this->blog_model->record_count();
                $config["per_page"] = 1;
                $config["uri_segment"] = 3;
                $config['num_links'] = 1;
                $config['query_string_segment'] = 'paginas';
                $config['page_query_string'] = TRUE;
                $config['display_pages'] = FALSE;
                
            
                $this->pagination->initialize($config);
            
                $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
                $data["pagination"] = $this->pagination->create_links();
                $data["results"] = $this->blog_model->get_paginas($config["per_page"], $page);
                
                $this->load->view('templates/head',$data);
                $this->load->view('templates/navbar',$data);
                $this->load->view("news/blog/index", $data);
                $this->load->view('templates/footer',$data);
} 


Here is my model(Blog_model):

PHP Code:

    class Blog_model extends CI_Model{
        // Connect to database //
        public function __construct(){
            $this->load->database();
            }
            
        // Get Posts from database //
        public function get_blog($slug=FALSE){
            if($slug===FALSE){
                // Post order, ASC-DESC Categorias/Tags tabels //
                $this->db->order_by('blog.id', 'DESC');
//                $this->db->join('categorias','categorias.id = blog.categoria_id');
                // /Post order, ASC-DESC //
                $query=$this->db->get('blog');
                return $query->result_array();
                }
                
                $query=$this->db->get_where('blog', array('slug'=>$slug));
                return $query->row_array();
            }
            
///Pagination
    public function record_count() {
    return $this->db->count_all("blog");
}

public function get_paginas($limit, $start) {
    $this->db->limit($limit, $start);
    $query = $this->db->get("blog");

    if ($query->num_rows() > 0) {
        foreach ($query->result() as $row) {
            $data[] = $row;
        }
        return $data;
    }
    return false;
}


        
        // Crear post //
        public function crear_post(){
            $slug=url_title($this->input->post('titulo'));
            
            $data = array(
                'titulo' => $this->input->post('titulo'),
                'slug' => $slug,
                'imagen' => $this->input->post('imagen'),
//                'autor' => $this->input->post('autor'),
                'fecha' => $this->input->post('fecha'),
                'contenido' => $this->input->post('contenido'),
                'categoria_id' => $this->input->post('categoria_id'),

            );
            
            return $this->db->insert('blog',$data);
            
            }
            
        // Borrar post //    
            public function delete_post($id){
            $this->db->where('id', $id);
            $this->db->delete('blog');
            return true;
        }
        // Actualizar Post //
        public function update_post(){
            $slug = url_title($this->input->post('titulo'));
            $data = array(
                'titulo' => $this->input->post('titulo'),
                'slug' => $slug,
                'imagen' => $this->input->post('imagen'),
//                'autor' => $this->input->post('autor'),
                'fecha' => $this->input->post('fecha'),
                'contenido' => $this->input->post('contenido'),
                'categoria_id' => $this->input->post('categoria_id'),

            );
            $this->db->where('id', $this->input->post('id'));
            return $this->db->update('blog', $data);
        }

        // Categorias //
        
//        public function get_categorias(){
//            $this->db->order_by('nombre');
//            $query = $this->db->get('categorias');
//            return $query->result_array();
//        }
            

        
        }
