Well in order to see {{desc_news}} it has already been rendered on the backend by running the PHP code of my server actions, and then passed to the front end in JSON format, which is then rendered by the front end component...
That is why i can only refresh parts of the page using these tools and not reload the whole page just to see a simple change. Users like interactivity and not heavy bloated with PHP (which is supposed to run on the backend and not on your page) pages, and i see this in every project i complete.
