How to make an input field for the quantity of goods on bootstrap 3?

Question

css

It is necessary to make such a field.

I found this code but it doesn't work. Is there a bug in the code or is there some other way to do it?

<div class="input-group quantity_goods">
  <input type="number" step="1" min="1" max="10" id="num_count" name="quantity" value="1" title="Qty">
  <input type="button" value="-" id="button_minus">
  <input type="button" value="+" id="button_plus">
</div>
