Your code is fine you have same id for more then one elementwhich is not valid. The event will be binded to firstelement with given id in the DOM. Use common class instead of id to bind the event. You can use class selectorto bind the event.
您的代码很好，您对多个无效元素具有相同的 ID。该事件将被绑定到第一个与给定id元素DOM。使用通用类而不是 id 来绑定事件。您可以使用类选择器来绑定事件。
$('.btn').click(function() {
var d = $(this).data('datac');
alert(d);
});

This should do the trick:
这应该可以解决问题：
var d = $(this).attr("data-datac");
Also, you need to change your HTML to give each element a seperate id. But it can be a tedious task to bind click events for a number of different ids. So i'd bind it to a seperate class. For example:
此外，您需要更改 HTML 以给每个元素一个单独的 id。但是为许多不同的 id 绑定点击事件可能是一项繁琐的任务。所以我会把它绑定到一个单独的类。例如：

<span class="btn btn-block btn-inverse btn-icon glyphicons home dateChanger" id="changeb1" data-datac="daily"><i></i>Daily</span>

<span class="btn btn-block btn-inverse btn-icon glyphicons home dateChanger" id="changeb3" data-datac="monthly"><i></i>Month</span>
<span class="btn btn-block btn-inverse btn-icon glyphicons home dateChanger" id="changeb4" data-datac="3Month"><i></i>3 Month</span>

You can't set all the elements a unique id. That's why it's happening only for the first element.
您不能将所有元素设置为唯一的id。这就是为什么它只发生在第一个元素上。

You can get attribute values of an element using the attrin jquerylike
您可以使用attrin jquerylike获取元素的属性值
$('.home').on('click', function() {
var d = $(this).attr('data-datac');
alert(d);
});
F.Y.I
供参考
If you will use id'sas selector you can only get one element while on a classyou can get reference all the elements containing that class
如果您将id's用作选择器，则只能获得一个元素，而在 a 上，class您可以获得包含该类的所有元素的引用

Use a unique id for each element
为每个元素使用唯一的 id
var d=$(this).attr('data-datac');
