过滤后首先显示选定的类

I am trying to sort the students after filter. After filtering the students button classes will change and text as like shown in the below image.

What I want is student with select-student has to come in first then reject-student students! How can I do this..?

PHP->HTML returns like this:

<tbody>

<tr>
<td><span><img></span><p>Rasmus1 Lerdorf</p><p><b>Hallticket</b> : S28J1</p></td>
<td style="line-height:45px">4</td>
<td style="line-height:45px">9</td>
<td style="line-height:45px">8</td>
<td style="line-height:45px">4.5</td>
<td><span id="stu28" class="btn btn-danger reject-student selection-class">Not Selected</span></td>
<td style="line-height:45px"><input class="overrideStudent" type="text" name="picomment[28]"></td>
</tr>

<tr>
<td><span><img></span><p>Bill Gates</p><p><b>Hallticket</b> : S29J1</p></td>
<td style="line-height:45px">9</td>
<td style="line-height:45px">10</td>
<td style="line-height:45px">8</td>
<td style="line-height:45px">6.1</td>
<td><span id="stu28" class="btn  selection-class btn-success select-student">Selected</span></td>
<td style="line-height:45px"><input class="overrideStudent" type="text" name="picomment[29]"></td>
</tr>

</tbody>

This is the Javascript code to select student:

success: function (response) {
    $(".selection-class").addClass('btn-danger reject-student');
    $(".selection-class").removeClass('btn-success select-student');
    $(".selection-class").text('Not Selected');
    $.each(response['students'], function(k, student) {
        $("#stu"+student.student_id).removeClass('btn-danger reject-student');
        $("#stu"+student.student_id).addClass('btn-success select-student');
        $("#stu"+student.student_id).text('Student Selected');
    });
    $("#success_message").show();
    $("#success_message").html(response['message']);

You can append() class "reject-student" to its parent selector and get needed result.
