title: How to change checkbox label value in DevEcoStudio Previewer according to selected language?
body: <p>I am using DevEco Studio 3.0.0.800, I created a select form element and added an option od datetime which launches a datetime picker. The default datetime picker changes according to language but the checkbox inside the picker remains in Chinese. I have tried changing it to multiple languages but it remains Chinese.</p>
  <p><strong>To Reproduce</strong></p>
  <p>Steps to reproduce the behavior:</p>
  <ol>
  <li>Add a select option of 'datetime' and a datetime picker</li>
  <li>Click on 'datetime'</li>
  <li>Click on '...' to change the language</li>
  <li>Open the datetime picker again</li>
  <li>The label for given checkbox is still in chinese</li>
  </ol>
  <p><strong>Expected behavior</strong></p>
  <p>The label for the given Checkbox should change according to the language selected.</p>
  <p>Here is my code:</p>
  <p><strong>index.hml</strong></p>
  <pre><code>&lt;div class=&quot;container&quot;&gt;
      &lt;select @change=&quot;selectChange&quot;&gt;
          &lt;option value=&quot;{{ item }}&quot; for=&quot;item in selectList&quot;&gt;
              {{ item }}
          &lt;/option&gt;
      &lt;/select&gt;
      &lt;picker id=&quot;picker0&quot; type=&quot;datetime&quot; value=&quot;{{datetimevalue}}&quot; selected=&quot;{{datetimeselect}}&quot; hours=&quot;24&quot; lunarswitch=&quot;true&quot;
              onchange=&quot;datetimeonchange&quot; oncancel=&quot;datetimeoncancel&quot; class=&quot;pickerdatetime&quot; show=&quot;false&quot;&gt;&lt;/picker&gt;
  &lt;/div&gt;
  
  </code></pre>
  <p><strong>index.js</strong></p>
  <pre><code>export default {
      data: {
          title: &quot;&quot;,
          selectList:[&quot;datetime&quot;],
      },
      selectChange(e){
          this.$element(&quot;picker0&quot;).show();
  
      },
      onInit() {
          this.title = this.$t('strings.world');
      }
  }
  </code></pre>
