Why rel="tooltip" and data-original-title not work?

Question

Good day.

I use bootstrap 3 and jquery 1.9

Code:

<span rel="tooltip" class="tir" data-original-title="Hello">
<span class="price">100</span><br>
<span class="description"><span class="bidNum">0</span> hi</span> 
</span>

Jquery:

<script>
$(function () {
    $("*[rel=tooltip]").tooltip();
});
</script>

Tell me please why code not work?

Where error?

Solution

Code above works fine here: http://bootply.com/93035. The issue was that the tooltip was showing up off screen. Adding a data-placement="auto" will solve this issue.
