Laravel 5.2 - Form do not submit -

sorry, i'm new laravel, have form:

<form action="/register" method="post">    {!! csrf_field() !!}         ....          <div class="form-group">    <button type="button" class="btn btn-default">register</button> </div> </form> 

and route is:

route::get('/register', 'auth\authcontroller@getregister'); route::post('/register', 'auth\authcontroller@postregister'); 

when click on register button nothing happen... form not submit, no errors etc.

can me ?

change

 <button type="button" class="btn btn-default">register</button> 

to

 <button type="submit" class="btn btn-default">register</button> 

and use dynamic url when deploy app server,then no error(s)

action="{{ url('/register') }}
