Sending msg.payload inside a vuetfy.js Template

I try to change the pages by clicking on images in my template. Recognizing the correct image when clicking works. Switching tabs with a dashboard button also works. Now I want a msg.payload with the name of the page to be posted when the image is clicked. I have already tested this function: this.send({payload:'Page1'}); . However, this does not post a message. Integrating the request into the HTML code was also unsuccessful. Switching with a button works with the help of msg.payload and the ui control.

Many thanks in advance
