CodeIgniter: redirect from embed view

I have a problem with redirection in embed view.

I'm, working on a project, where security is very important. I use codeigniter and bootstrap. I have main view, which includes navbar and some other html. In that main view i have <div id="change"> which i am changing via button group. With those buttons I am calling functions in controller with jQuery which (functions in controller) contains $this->load->view('pages/something', $data); When i press on one of those buttons <div id="change"> is changed and in it, a view is shown and link is not changed, so main view remains as it is.

<script>
var vari = "<?php echo $data['vari']; ?>";
$(function() {
    $("#btn1").click(function() {
        $("#change").load("Controller/function1/"+vari)
    })
    $("#btn2").click(function() {
        $("#change").load("Controller/function2/"+vari)
    })
    $("#btn3").click(function() {
        $("#change").load("Controller/function3/"+vari)
    })
    $("#btn4").click(function() {
        $("#change").load("Controller/function4/"+vari)
    })
    $("#btn5").click(function() {
        $("#change").load("Controller/function5/"+vari)
    })
})

When i do things in one of those embed views, sometimes i want to use redirect('/Controller', 'refresh');. Problem is, that when i use it, just embed view is changed - redirected, but main view with navbar and button group is still there.

How can i achieve, that when i call redirect() in "embed controller function", main view is changed, not only <div id="change">. Is this possible? If not with my method - what could be alternative solution, how can you redirect whole page from "embed controller function" (sorry i dont know how to name this =D).

I will appreciate any help. Thanks!
