Icons linked to scripts

There's a better solution for your task, you can enable "Show control" for that element and add additional class "mydimmer" and style it via CSS.

Here's a small example to start from:
   

Code:

.usermode .mydimmer .btn {
 text-shadow: none;
 color: transparent;
 background-size: 60%;
 background-repeat: no-repeat;
 background-position: center center;
}
.usermode .mydimmer .dimmer-down {
 background-image: url('/scada/resources/icons/plus-minus-off.png');
}
.usermode .mydimmer .dimmer-up {
 background-image: url('/scada/resources/icons/plus-minus-on.png');
}

Also, you can enable "No bus write" for visualization elements, this will not send a KNX telegram to KNX/TP, only internally and to KNX/IP if enabled.
