Hi, this trello series is amazing.  I am not sure if I am allowed to ask some specific coding questions here but here goes. 

I am using this each as a budgeting card such that each card has an amount and below that supposedly a running balance from the amounts from the cards on the top. The idea is to make the cards draggable to the order of payment and to park some expenses on other columns which are not for processing. I was able to find a way to add a running amount field in each item and update each item with the latest running amount as the order is being updated and stored. The problem is it is not being sent back to view the updated running amount without reloading the page. Can you suggest some episodes to watch for this?
