How to use text input in IWSDK with UIKitML

I have tried using direct input element queries, but inputElement.properties.value or inputElement.value is always empty.

After a lot of debugging, I found that the input can be captured through direct signal access, like below:

      const doc = this.panelDocument;
      const textInput = doc.getElementById('checklist-text-input');
      if (textInput && textInput.currentSignal) {
        const newText = String(textInput.currentSignal.v ?? '').trim();
        item.text = newText;
      }

However, this seems like a hack, and I did not find any way to set the input value dynamically through any properties. I would like to know if there is a proper way to manipulate the input with UIKitML.
