Route::get with options and function not working properly in laravel

I wan to use Route::get with route options, function and where. following is my route code:

Route::get('/view/{id}', array('uses' =>'BookController@view','as' => 'book.view'), function($id)
{
    die('hello');

})->where('id', '[A-Za-z]+');

so when i call url view/4 it will open 404 page and when i call view/abc it will run controller code but in neither case function code is not executing.

How can i fix this?
