Laravel MethodNotAllowedHttpException

I have Permission Roles that i want to delete when i click on them so i did a route that takes role id and permission id

Route::post('management/role-permission/{role_id}/{permission_id}', 'RolePermissionsController@Delete');

And i get this route from link from my html:

 @foreach($data as $dat)
                <div class="col-xs-3 text-center">
                    <form  action="/management/role-permission//" method="POST">
                        {!! csrf_field() !!}
                        
                        <button onclick="return confirm('Are you sure?')"  class="btn turquoiseButton btn-margin full-width"><i class='fa fa-close close-btn'></i>  </button>
                    </form>
                </div>

@endforeach

And the route goes to this controller :

 public function Delete( $role_id ,$permission_id)
{
    $role_permission=DB::table('permission_role')
        ->where('role_id' ,$role_id)
        ->where('permission_id' ,$permission_id)
        ->delete();
    return Redirect::to('/management/role-permission/'.$role_id . '/list');
}

But i keep getting this error for no reason
