$.ajax({

type:'POST',
contentType: false,
processData: false,
success:function(data){
$("#addModal").hide();
window.location.reload(true);
}
});
}
return false;
});
Controller
public function insert(){
$nama = Input::get('nama');
$this->nama = Input::get('clientName');
$query = DB::table('profile')->insert(array('nama'=>$nama));
}
ROUTES
Route::get('form/insert', 'FormController#insert');

Answer 1

You need to define the method you will be using to submit the form as. There is no method mentioned so it is submitting its default, GET.
so you form tag should look like this:
<form method="POST" id="tambahform" class="form-horizontal" role="form">
In the url, you need to give it a full path or else it will give a 404 not found error. Take a look at this code:
e.preventDefault();
var formData = $(tambahform).serialize(); //<--use Serialize
$.ajax({
url:'form/insert.php', //<--add full path including the files extension here
data:formData,
type:'POST',
contentType: false,
processData: false,
success:function(data){
$("#addModal").hide();
window.location.reload(true);
}

Answer 2

Instead of this
Route::get('form/insert', 'FormController#insert');
use this
Route::post('form/insert', 'FormController#insert');
