What is the correct way to pass a property value into another property within a Polymer element?

I have an array of objects called searchResults. I am trying to display only the object based on the index that is clicked.


    Polymer({
        properties: {
            data: {
                type: JSON,
                value: [],
                observer: 'markerClicked'
            },
    
            selectedRetailer: {
                type: Number,
                value: 0,
            }
        },
        
        markerClicked: function(e) {
            this.selectedRetailer += 1;
        }
    })

The code above is not functioning as expected and I'm unsure why.

Essentially, I want to use selectedReatailer as the index for the array. How can I achieve this?

Thanks
