todo-list.js is not working

I've followed till the video#34 properly and done as instructed, but whenever now I add a new item I can't see it in the app , also same with the deleting the item from todo list .

I think I forget to add/include the todo-list.js file in the .ejs(views), does it concern to that or not? Please guide

Start by reproducing the add and delete failures described after video #34, then inspect todo-list.js and the relevant .ejs view to confirm how the script is included. Trace whether the view loads the script and whether both actions reach it. Done means newly added items appear in the app and existing items can be deleted.
