Code:

function atribuido($tabela,$atributo,$campo)
    {
        $query = $this->db->query('SELECT * FROM '.$tabela.' WHERE '.$atributo.' = "'.$campo.'"');
        if ($query->num_rows() > 0){
            echo true;
        } else {
            echo false;
        }    
}

The ajax request gets the string output, not the value. Echoing false doesn't return anything, and echoing true just returns 1. Try echoing the string instead.

Since this request doesn't need anything else, you can make debugging easier by killing the script to avoid any unexpected output.

Code:

if ($query->num_rows() > 0)
{
    exit('true');
}
else
{
    exit('false');
}
