dueChange event for duet picker not working with Ionic 5 / Vue 3

[adityasharma7]

Describe the bug
I am using Duet Date Picker in the Ionic 5/ Vue 3 application. The event listener for the duetChange is not working for me.

Here is my code snippet:

<duet-date-picker @duetChange="handleInput($event)"identifier="date" :localization.prop="localisation" direction="left"></duet-date-picker>


handleInput(e: any) {
      console.log("e", e);
      this.$emit("input", this.content);
    }

I have even tried following listeners:

v-on:duetChange="handleInput($event)" 

v-on:change="handleInput($event)" 

@change="handleInput($event)"

Is this the right way to add an event listener or am I missing something?

I am seeing the following warnings in the codesandbox console...

[Vue warn]: The `isCustomElement` config option is only respected when using the runtime compiler.
If you are using the runtime-only build, `isCustomElement` must be passed to `@vue/compiler-dom` 
in the build setup instead- for example, via the `compilerOptions` option in vue-loader: 
https://vue-loader.vuejs.org/options.html#compileroptions.

Seems like it might be related to the issue you have? I don't know vue at all, so I am taking a bit of a guess here, but it seems relevant
