Bootstrap 5 content function only gets called once

[SoftCircuits]

I have the following JavaScript/jQuery code that creates and initializes a number of Bootstrap popovers.

I need the text to be updated each time it is shown, so I thought being able to set content to a function would be perfect. However, this function only gets called once per popover. So instead of updating each time it is displayed, it just keeps showing its initial value.

// Initialize example conversion popovers
$('img.example-conversion').each(function() {
    new bootstrap.Popover(this, {
        placement: 'right',
        trigger: 'click focus',
        html: true,
        title: 'Quantity Divisor',
        content: getPopoverContent,
    });
})

var count = 1;
function getPopoverContent() {
    return count++;
}

I need to update the text every time it is displayed. Does anyone know how to make that work?

I'm using Bootstrap 5.1.
