How to get the parent of the Bootstrap slider which triggers the change event

I have two Bootstrap sliders, initialized and ready. I have attached change event to them, but I am unable to get which slider is changing, as change event gives me an object containing newValue and oldValue. I need to get the event.target to find the parent of the slider which is triggering the change event.

Here is the code that I have so far :

HTML FIXTURE

<div class="container-fluid">
  <div class="slider-container">
    <span id="slide-label">Example slider label</span>
    <input class="slide" id="slide_1" type="text" />
  </div>
</div>

<div class="container-fluid">
  <div class="slider-container">
    <span id="slide-label">Example slider label</span>
    <input class="slide" id="slide_2" type="text" />
  </div>
</div>

JS

let slide_arr = [
            {
                id: 'slide_1',
                min: 1,
                max: 4,
                step: 1,
                value: 1,
                tooltip: "hide",
                ticks: [1, 2, 3, 4],
                ticks_labels: ["item a", "item b", "item c", "item d"]
            },
            {
                id: 'slide_2',
                min: 1,
                max: 4,
                step: 1,
                value: 1,
                tooltip: "hide",
                ticks: [1, 2, 3, 4],
                ticks_labels: ["item 1", "item 2", "item 3", "item 4"]
            }];

        let slider_instance = [];

        for (let index = 0; index < slide_arr.length; index++) {
            const slide_obj = slide_arr[index];
            slider_instance[index] = new Slider(`#${slide_obj.id}`, slide_obj);
        }

        for (let index = 0; index < slider_instance.length; index++) {
            const slider = slider_instance[index];
            slider.on('slideStart', function (e) {
                console.log('slideStart')
                console.log(e);
            });
            slider.on('slideStop', function (e) {
                console.log('slideStop')
                console.log(e);
            });
            slider.on('change', function (e) {
                console.log('change')
                console.log(e);
            });
            slider.on('slide', function (e) {
                console.log('slide')
                console.log(e);
            });
        }

I have tried a lot of events and none are helping.

I have made this Fiddle to demonstrate the problem.

To get the target you're changing, you can use slider.$element and slider.$sliderElem in your case.

slider.on('change', function(e) {
    // I think this is what you actually want (#slide_1 or #slide_2)
    console.log(slider.$element)

    console.log(slider.$sliderElem) // This is the horizontal slider
});
