Does any one know how to generate an ion-card?

Hello, I want to generate this code:

<ion-card>
    <ion-card-header>
        <ion-card-title>Title</ion-card-title>
        <ion-card-subtitle>Subtitle</ion-card-subtitle>
    </ion-card-header>
</ion-card>

But I dont know how to generate.

Firstable, I created a concept called IonCard with the properties "Title" and "Subtitle" and also I created a concept editor for the concept of IonCard that has the 2 properties of the concept (title and subtitle).

The problem comes when I created a template declaration, I dont know what to write because the code that I have previusly written above I cant write it.

Can you help me?? Please
