Input Checkbox Doesn't Submit

I have 2 switches inside a Laravel Form where I already give default value as 0. As soon as I submit, I got all values in my form, but those 2 switches.

I'm wondering if I did anything that I'm not suppose to.

HTML

<div class="col-xs-2">
    <label class="control-label">Multisite VPN</label> <br>
    <input type="checkbox" name="vpn" id="vpn" value="0">
</div>

<div class="col-xs-2 mb10">
    <label class="control-label">UPnP</label> <br>
    <input type="checkbox" name="upnp" id="upnp" value="0">
</div>

---

JS

<script type="text/javascript">

    var vpn  = $('#vpn');
    var upnp  = $('#upnp');

    //Ativate the Switches
    vpn.bootstrapSwitch('size', 'mini');
    upnp.bootstrapSwitch('size', 'mini');


    vpn.on('switchChange.bootstrapSwitch', function (event) {
        if (vpn.is(':checked')) {
            vpn.val(1);
        } else {
            vpn.val(0);
        }
        console.log('vpn: ' + vpn.val());
    });

    upnp.on('switchChange.bootstrapSwitch', function (event) {
        if (upnp.is(':checked')) {
            upnp.val(1);
        } else {
            upnp.val(0);
        }
        console.log('upnp: ' + upnp.val());
    });

</script>

If

I turn 2 those switches ON, I seems to get it

array:19 [▼
  "_token" => "brXS4YGTGnD7QzkHuvbAyZsmSC8nUB9vxywB4bXK"
  "name" => "silver"
  "vpn" => "1" <--------- HERE 
  "upnp" => "1" <--------- HERE
  "p_max_up" => "128"
  "p_max_down" => "128"
  "p_ip" => "111111111"
  "p_netmask" => "2222222222"
  "p_max_user" => "50"
  "p_dns" => "333333333"
  "p_dns2" => "4444444444"
  "g_max_up" => "128"
  "g_max_down" => "128"
  "g_ip" => "5000000"
  "g_netmask" => "6000000"
  "g_max_user" => "22"
  "g_dns" => "888888888"
  "g_dns2" => "9999999999"
  "g_portal" => "http://ift.tt/29xbb1D"
]

Why that 2 inputs submit only if the switches is ON/True ?
