As long as you are using new Chart() constructor, accoding to the documentation destroy method should be called before the canvas is reused for a new chart.

In your case it should work as follows

if(window[configs.selectorId] && window[configs.selectorId] !== null){

    if (typeof window[configs.selectorId].destroy === 'function') {
        window[configs.selectorId].destroy();
    }
    delete window[configs.selectorId];
}

Here is a snippet I’ve created on the basis of your code:

I’ve just changed your random data API to locally random generated data

Please, let me know if my answer is not clear enough or you need some additional information
