I have no issues with assigning a datasource to a listbox:

            .done(function (result) {
                var lstSignedUp = document.getElementById('lstSignedUp').ej2_instances[0];
                lstSignedUp.dataSource = result;

But how do I un-assign the datasource so the listbox displays no items?
I tried this, but nothing happens,

        let lstSignedUp = document.getElementById('lstSignedUp').ej2_instances[0];
        lstSignedUp.dataSource = null;

I've also tried:
        lstSignedUp.listData = null    //again the list box does not empty.

Hi Mike, 
Good day to you. 
We have checked your provided code snippet and we suggest you use refresh method instead of dataBind to clear the ListBox as like in the below code example, 
Code Example 
function onCreate() { 
    var obj = document.getElementById('listbox').ej2_instances[0]; 
    obj.dataSource = null; 
For your convenience, we have prepared a sample and the same can be downloaded from below link, 
Could you please check the above sample and get back to us if you need any further assistance on this?
