how to update listview item content periodically

Question

I have created groups. Now I want to change the content of win-item periodically. For example, in the above image wherever its written "Sorbet" it should changed to some other value and it should keep changing after some period. I have tried by using secondary tile update but it is reflecting at the start of the app not at the proper place though I have given a div id. I am using javascript, html5 and css only not c# and dot net.
