WebObject can not access the updated variable of the text entry when they are on the same slide

Hi,

I'm using PDFMake js library to generate PDF.

 

I'm following this example, it works very well:

The issue appears when I have the text data entry and the webobject on the same slide like  in this image:

When the user types something and then click "Download PDF" button, the latest typed text is not reflected in the downloaded PDF unless  you leave the slide and get back to it again, then click the download button again.

 

Why the WebObject can not access the updated variable of the text entry when they are on the same slide?

 

Thank you.
