cannot POST json data using Angular

I am finished my first online calculator and cannot understand how to send the data to server. I am using Laravel 5 + angularjs

in my blade.php I have this

    {!! Form::open(array( 'class' => 'calculator', 'name' => 'calculator', 'files' => true, 'ng-app' => 'SaunaDoorCalc', 'ng-controller' => 'SaunaDoorCalcController')) !!}
@if(Session::has('message'))
    <div class="alert alert-info"></div>
@endif
@if(Session::has('errors'))
    <div class="alert alert-info">@foreach($errors->all() as $error)<br>@endforeach
</div>
@endif

    <input name="calc" ng-model="calc" type="text" value="saunadoor" disabled>

                  alert('Form is not valid');
            }

        }

  });

in my routes.php

Route::get('izdeliya-iz-stekla/{cat}/{item}', 'StekloController@getItem');
Route::post('izdeliya-iz-stekla/{cat}/{item}', ['as' => 'order', 'uses' => 'StekloController@order']);

in my StekloController

public function order(CalculatorRequest $request) 
{
    $input = Input::json();
    return Redirect::back()->with( dd($input) );      
}

Then after click on submit button I have

ParameterBag {#211 ▼
  #parameters: []
}

So for me it seems that I'm trying to send empty object. But I cannot understand how to tune Angular script
