title: Bootstrap doesn't use "checked" attribute of checkbox
body: <p>I am using Bootstrap. I have a table with a checkbox in a header and in each collumn. I am trying to make "check all" functionality on jQuery, but it seems that bootstrap does not use checked attribute. As I see, it adds span tag around my checkbox and adds a class 'checked' to it. Is there any possibility to work with checked attr, or I must forget about it and write class checking and switching?</p>
  
  <p>Below goes the part of code from the result HTML:</p>
  
  <pre><code>&lt;td&gt;
    &lt;div class="checker"&gt;
      &lt;span class=""&gt;
        &lt;input type="checkbox" class="payout_check" style="opacity: 0;"&gt;
      &lt;/span&gt;
    &lt;/div&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>This is unchecked one. The it is checked, third row changes to:</p>
  
  <pre><code>&lt;span class="checked"&gt;
  </code></pre>
