Ionic 4 Custom input inside <ion-item>

My application was created using the ionic-cli 5.0.2. I have the above structure for my form:


Notice that password input consists into a custom element that I have created, wish is basically an <ion-input> with extra behaviors.

The thing is that the input is not properly rendering inside the <ion-item> due to the <password-input> tag that wraps it.

The recommendation for Ionic v3 is to put an item-content property to my custom tag but this is not working. I try to put slot="item-content" property but no success either.

Any thoughts or help on how to get the custom input working with list item would be great.
