Increment/Decrement uses the value of the first input

On a click action and want to increment values of all inputs and reset the closest input to 0.

I created a fiddle to demonstrate:
https://jsfiddle.net/oj6c53bt/1/

I expect all inputs to have unique values at some point, but all values are synced with the first input of the selection.

```HTML

Click me third



Click me second



Click me first
