passing variable from controller to view page shows undefined variable

I've passed a variable temp from controller to view page. While debugging the search method, I am getting data from database to the variable temp. When I pass this variable to view page, it is showing error as

 ErrorException (E_ERROR)
Undefined variable: temp (View: C:\xampp\htdocs\laravel\lsapp\resources\views\pages\MySearch.blade.php)

I doubt the error is most likely due to route configuration but I am not sure. There might be other errors too. But the process of passing variable from controller to view page is same, but also I am getting the error.

controller code block

public function searchDev()
    {
        return view ( 'pages.MySearch');
    }
public function search(Request $request)
{
    $UserName = $request->input('MyName');

    if($UserName != ""){
        $temp = temp::where ( 'NAME', 'LIKE', '%' . $UserName . '%' )->get (['id','NAME','CONTACT','TEMP_ADDRESS']);
        if (count ( $temp ) > 0)
        {
            /*
                getting result from database
                dump($temp);                 
                return response()->json($temp);
                 */
            return view('pages.MySearch', [
                'temp' => $temp
            ]);
        }                
        else
        {
            return view ( 'pages.MySearch')->with('alert-danger', 'Sorry No details found');
        }

    }
}

view page code block

@foreach($temp as $data)
 <tr>
      <td>  </td>
     <td>  </td>
     <td>  </td>
</tr>
@endforeach

route code

Route::get('/MySearch','MyController@searchDev');
Route::post('/MySearch','MyController@search');

The error is general, but I can't debug the error what is the cause of the error. Please help!!!
