Laravel 5.8 single routing but multiple controllers

I'm using this method for using different controller for my route but didn't work

here is my route code

Route::get('{slug}', ['middleware'=>'isPage', 'uses'=>'PageController@view'])->name('viewPage');


Route::get('{modelName}', ['middleware'=>'isUser', 'uses'=>'ModelController@view'])->name('viewModel');

and here is middleware code for isUser

use Closure;

use App\ModelProfile;
class isUser{
 public function handle($request, Closure $next)
 {
    $slug = $request->route()->parameter('slug');
    $model = ModelProfile::where([
        ['slug', $slug],
        ['is_status', 'ACTIVE'],
        ['is_deleted', 'NO']
    ])->count();

    if($model > 0){
        return $next($request);
    } else {
        abort(404);
    }
}

and here is my middleware code for isPage

use Closure;

use App\Page;
class isPage{
 public function handle($request, Closure $next)
 {
    $slug = $request->route()->parameter('slug');
    $model = Page::where([
        ['slug', $slug],
        ['is_status', 'ACTIVE'],
        ['is_deleted', 'NO']
    ])->count();

    if($model > 0){
        return $next($request);
    }
 }
}

In kernel.php

'isPage' => \App\Http\Middleware\isPage::class,
'isUser' => \App\Http\Middleware\isUser::class,
