insert_bottom
Inserts HTML after the contents of an HTML element.
Adds a template or a literal HTML text after the existing content.
Example:
<div id="mydiv"><p>Bye Bye.</p></div>
{% button text="hello" action={insert_bottom target="mydiv" text="<p>Hello World!</p>"} %}
After the button is clicked, the contents of the div will be <p>Bye Bye.</p><p>Hello World!</p>.
Another example, now rendering a template:
<ul id="mylist"><li>Some item</li></li>
{% button text="hello" action={insert_bottom target="mylist" template="_list_item.tpl" id=42} %}
This insert the output of the template _list_item.tpl below the existing <li/>. All arguments to the update action are also arguments to the template.
