Laravel 5.0 data Insertion using bootstrap3 form

I am trying to insert data into my database name Client using a bootstrap form. But if I click submit button the page just directed to newClintForm page without inserting any value into the Client database. I am using laravel version 5.0. This is the Form part of newClientFormblade template -

<form role="form" method="post" action="{{url('clients/newClientForm')}}">

                                <input type="hidden" name="_token" value="{{csrf_token() }}">

                                <div class="form-group">
                                    <label>Name</label>
                                    <input class="form-control" name="ClientName" placeholder="Erfan">
                                </div>

                                <div class="form-group">
                                    <label>Client ID</label>
                                    <input class="form-control" name="ClientID" placeholder="Ect112">
                                </div>

                                <div class="form-group">
                                    <label>Phone No.</label>
                                    <input class="form-control" name="Phone" placeholder="01XX-XXXXXXX">
                                </div>
                            <button type="submit" class="btn btn-default">Submit Button</button>
                            </form>

instead of csrf_token() I tried Session::token() but didn't help either.

This is my controller part-

public function newClientFormIndex(){
    return view('clients.newClientForm');
}
public function store(Request $request)
{

    $client = new Client();
    $client->ClientID = $request->ClientID;
    $client->ClientName = $request->ClientName;
    $client->Phone = $request->Phone;
    $client->save();

}

this is the Model part-

class Client extends Model {

protected $table = 'clients';
public $timestamps = false;
protected $primaryKey = 'ClientID';
protected $fillable = ['ClientID', 'ClientName', 'Phone'];

}

I can't find where the error is ! Any kind of help is appreciated.
