Deep watchers in vue for data rendered in a v-for loop

Hi there … I need some help with setting up a watcher on a value inside of an array of objects rendered using v-for loop see this code pen https://codepen.io/neenus/pen/VwazMVy I know the example is stupid but it’s pretty similar to my situation… basically I want to set a watcher on the count value to be fired individually whenever any of the values change.

is this doable with vuejs watchers?? I appreciate any help I can get.

Thanks
