powerapp – How can I insert selected Listbox items as a new record in to a common data service table

I have a PowerApps canvas App and I have a requirement of creating new records for all selected listbox items in to a table. I am acually trying to implement a many to many relationship scenario

my Listbox name is: ListBox1 and my table name is ContactsTable inside the page I have put a button and on click of button I put the following PowerApps logic:

  ForAll(ListBox1.SelectedItems,Patch(ContactsTable ,Defaults(ContactsTable),{EmpID:2,Name:ListBox1.Selected.Name}));

it creates the last selected item repeated based on the number of items i select from listbox any Idea would be great.
