How to execute a directive right when rendering DOM in VUE

Question

I'm trying to define a directive and I need to be executed right when DOM is rendered.

I was reading about different hooks, but inserted () or update () hook doesnt do the trick. This is my directive:

Vue.directive('validation-directive', {
  bind (el, binding, vNode) {
    addValidation(el, binding)
  },
  inserted (el, binding, vNode) {
    addValidation(el, binding)
  },
  stopProp (event) { event.stopPropagation() }
})

function addValidation (el, binding) {
  console.log(el)
}

Anyone knows how to do it? Thanks!
