jQuery UI & Knockout problem with Sortble

I have found this: [login to view URL] Which i need to work in a knock out template I have a fiddle alreay setup to got which can be found here: [login to view URL] fork it and apply the following changes:: 1) Change the domready js into a knockout viewmodel 2) Change the html into knockout view 3) Connect the view with the viewmodel 4) Create model column with a title and show the title above the column (this is additional reuirement the base version does not have this) 5) The three div with class ".column" need to be created dynamically based on an observable collection of model column which should be defined in the viewmodel 6) Create model portlet with property title and property content 7) The five sortable div with class "portlet" should be created dynamically based on an observable collection of portlet which should be defined in the viewmodel 7) The knockout version should work exactly as the pure jquery ui version
