Dynamic filename failes due to genOpts js issue

[Er-Kalpesh]

Prerequisites

So I want dynamic filename when I export grid. Like I need all the filter I have applied before grid export. So I have used code like

$output = Helper::array_to_pipe($_GET,'_', [], false,'_');
$filename = "Export_".$page_title."_".$output."_".date('Y-m-d'); 

and inside the config: 'filename' => \Yii::t('kvgrid', $filename),

so it's working perfectly fine when I don't use ajax or pjax. but issue comes when I use ajax and result of it getting error of "The parameters for yii2-grid export seem to be tampered. Please retry!"

Steps to reproduce the issue

1. So on ajax request it comes to my code and generates new filename from the query params
2. Comes to file: \vendor\kartik-v\yii2-grid\src\GridView.php protected function registerAssets() ...

   foreach ($this->exportConfig as $format => $setting) {
               $id = "jQuery('#{$gridId} .export-{$format}')";
               $genOpts = Json::encode(
                   [
                       'filename' => $setting['filename'],
                       'showHeader' => $setting['showHeader'],
                       'showPageSummary' => $setting['showPageSummary'],
                       'showFooter' => $setting['showFooter'],
                   ]
               );
               $genOptsVar = 'kvGridExp_' . hash('crc32', $genOpts);
               $view->registerJs("var {$genOptsVar}={$genOpts};");
               $expOpts = Json::encode(
                   [
                       'dialogLib' => ArrayHelper::getValue($this->krajeeDialogSettings, 'libName', 'krajeeDialog'),
                       'gridOpts' => new JsExpression($gridOptsVar),
                       'genOpts' => new JsExpression($genOptsVar),
                       'alertMsg' => ArrayHelper::getValue($setting, 'alertMsg', false),
                       'config' => ArrayHelper::getValue($setting, 'config', []),
                   ]
               );
               $expOptsVar = 'kvGridExp_' . hash('crc32', $expOpts);
               $view->registerJs("var {$expOptsVar}={$expOpts};");
               $script .= "{$id}.gridexport({$expOptsVar});";
           }

3. And when I debug it shows correct filename here too but it's not reflecting the browser. still, in firefox console, I can see old "genOpts" values. also in \vendor\kartik-v\yii2-grid\src\assets\js\kv-grid-export.js Its retrieving old "genOpts" values when I use pjax.
