How do you add a visual indicator such as a spinner and a tick when you save a new task in the example below.
Basically when I click the save button the following should happen:
Save button should become invisible
Cancel icon should become invisible, a spinner should appear instead to indicate something is happening
A tick icon should briefly appear if successfully saved and then disappear before displaying the delete icon.
The v-show that i'm using doesn't seem to work when I try to replicate a sleep effect to display the spinner when the updateTask() method is fired?

* UPDATE *
So I've managed to update this - see the new fiddle, to provide the functionality required. But it's a very messy solution - code is all over the place. Anyone know of a better/cleaner way to refactor and achieve the same functionality and perhaps provide a fade in/out affect to the tick when you save the element?
