what does the word "bind" mean in this context?

I'm lost as to why we need to "bind" editTask, deleteTask, etc.

The event binding allows you to add an event handler for a specified event so that your chosen JavaScript function will be invoked when that event is triggered for the associated DOM element. http://knockoutjs.com/documentation/event-binding.html

Thank you for clarifying that. Your explanation was better than the instructor (he didn't explain the bind event at all).

Hello Johnny,

I am relatively new to JavaScript but I think this is what it means: I believe that the word "bind" means that you are grouping different actions together to act as one event. So in this context, editTask selects the edit button and allows the user to edit it if "edit-mode" is on, and if "edit-mode" is not on, then the user can't edit.

If a "bind" was not in place, then there is no actions that perform together.

I hope this makes sense.
