I have a Bootstrap popover that I want to attach to an element that has a conditional render; therefore, I must trigger $().popover() after the element has been attached to the DOM.
Is there a way to trigger a callback after a v-if statement inserts the elements into the DOM?

The best way to force Vue to re-render a component is to set a :key on the component. When you need the component to be re-rendered, you just change the value of the key and Vue will re-render the component.
mounted () : it will executed before creating the component. created () : it will executed after creating the component for render.
$emit to emit a custom event. Let's take a look at an example where we have MyTextInput. vue that contains a label and a text input. Whenever the text changes, we want to emit an event with the uppercased value of our input. Instead of calling $emit from our template, we can call a component method instead.
Vue events don't bubble the component tree on their own. However when writing wrapper components this can be the desired behaviour. This code registers a global bubble directive which allows to re-emit all given events: Let's say we want to bubble events start , accelerate and brake of our component Car .
Use this in vuejs 2:
updated: function() {
$('[data-toggle="tooltip"]').tooltip();
},

Vue.nextTick() defers the execution of the callback to be executed after the next update of the DOM, see: VueJS API reference
