ajax not response in my laravel

i make a crud in laravel using ajax, but i have problem there are can't response my script.

this is my form:

{!!Form::Open()!!}
{!!Form::text('judul',null,['id'=>'agenda', 'class'=>'form-control','placeholder'=>'Judul'])!!}
{!!link_to('#',$tittle='Submit', $attributes = ['id' => 'okModal', 'class'=>'btn btn-primary'], $secure = null) !!}
{!!Form::Close()!!} 

and this is my script.js

    $("#okModal").click(function(){
    var datas = $("#agenda").val();
    var route = "/agenda";
    var token = $("#token").val();

    $.ajax({
       url: route,
        headers : {'X-CSRF-TOKEN':token},
        type: 'POST',
        dataType: 'json',
        data: {agenda :datas}
    });
});

when i run and view the inspect manager in chrome browser, is not response the /agenda . whereas we know my button link to route:/agenda.

this is my controller :

public function store(Request $request)
{
    if($request -> ajax()){
        return response()->json([
            "pesan" => $request->all()
        ]);
    }
}
