How to sort?

[webdeb]

Hi I would like to implement a possibility to sort my Items.

Lets say I have data with timestamps:

[{
  html: '<h3>Item title</h3>',
  data: timestamp
}]

I am requesting the data periodically.. And the server response contains older & newer items..

I would like to sort them and put them to the right place, instead of just appending them to the list. What would be your suggestion to implement that? Thanks a lot
