Uncaught TypeError: Cannot read property 'Checked' of undefined - ReactJS

Question

I am trying to create a simple a TODO list app in ReactJS. My basics of React are not very clear so I am stuck here.

Answer 1

Make createItem a method of TodoList class. The "this" reference is not being resolved as right now its a local function of render method. On a side note, React follows camel casing for handlers. Please rename the Clicked method to onChange, onChecked or onCheckClicked.
