SELECT DYNAMIC CODEIGNITER - AJAX

Hello! I have the following tables:

tbl_encargo
tbl_category
tbl_encargo

Since in tbl_lacamento there is a field ( id_categoria ) that receives the ids of tbl_categoria and tbl_categoria receives its id ( id_juros ), coming from the tbl_juros table.

I am using codeigniter and I want to display in a field hidden <input type="hidden" id="juros" name="txt_juros" placeholder="juros" title="juros"/> in view lançamento all categories of tbl_categoria , and I want to dynamically display all ids_juros related to tbl_categoria .

Can you lead me to some code that does this? I think this would work for ajax, I tried to relate by following an example of states and cities, but I could not because the related ids are in the parent table.

What I have today, displays only categories. Below a view

<select id="categoria" class="form-control" name="sel_id_categoria" >
    <?php foreach ($categoria as $categoria) {
       echo '<option value="'.$categoria->id.'">'.$categoria->descricao.'</option>';
    } ?>
</select>

Controller code launching

//Listar Categorias ativas Receitas e Despesas
$this->load->model('app/Categoria_model');
$this->data['categoria'] = $this->Categoria_model->obter_ativo('tbl_categoria', 'tbl_categoria.id,tbl_categoria.descricao');

Code no model Category_model

	//Listar ativos
  var $tabela = 'tbl_categoria';	
	function obter_ativo($tabela,$campos)
	{        
        $this->db->select($campos);
        $this->db->from($tabela);
        $this->db->where('situacao',1);
        $query = $this->db->get();
        return $query->result();;
  }

I would do it as follows:

<select id="categoria" class="form-control" name="sel_id_categoria" >
    <?php foreach ($categoria as $categoria) {
       echo '<option value="'.$categoria->id.'">'.$categoria->descricao.'</option>';
    } ?>
</select>

<input type="hidden" name="juros" id="juros" value="">


<script>
    $("#categoria").change(function(){
        var categoria = $("#categoria").val();
            $.ajax({
                url: "ajax/buscar_juros", // Metodo de buscar juros
                type: "POST",
                data: {categoria:categoria},
                success: function(data){
                    $("#juros").val(data);
                }
            });
    });
</script>

ajax / seek_rights

public function buscar_juros(){
    $this->db->where('categoria', $this->input->post('categoria'));
    echo $this->db->get("juros")->row('taxa_juros');
}
