I am dynamically adding the content of "div" in jquery it is added in DOM. but in view page source i can't see dynamic content of an element

```
<div id="pdf"></div>

("#btn").click(function(){
$("#pdf").html("ffff");
});

```

how can i get updated page source after made dynamic changes. it is added in DOM but page source doesn't have the content ? why ?

Thanks,
