I am trying to add html tags dynamically through jquery in django.

$("#div1").append("<h3> Hey !! </h3>");

$("#div1").append("<br/>");

But they are not working.

However normal text is getting appended properly like

$("#div1").append("Hey i am here");

I even noticed that some of the tags wern't working outside script like

<br>  so i had to replace it with  <br/>

also had to apply closing tag for input and also &nbsp is not working.

what is wrong???
