     <div class="sortable-sections">
            <fieldset class="section draggable" id="flSectionType">
                <div class="btn-drag section-handle hidden-view">
                </div>
                <div class="section-header">
                    <span class="section-label">Job Requirements</span> <a class="section-info" href="#more-info"
                        title="Minimum Education, Minimum Work Experience, Required Licenses/Certifications, Required Skills, Knowledge, and Abilities needed to perform the job.">
                        ?</a>
                </div>
                <div class="sortable-items">
                </div>
                <a class="section-add-item hidden-view" id="addJR" href="#add-item" data-item='{"id":"addJR","template":"requirement","item_type":"Job Requirement"}'>
                    Add a new Job Requirement</a>
            </fieldset>
       <fieldset class="section draggable">
       </fieldset>
       <fieldset class="section draggable">
       </fieldset>
     <div>

The above code will generate a list of sections which can be dragged with in the sortable-sectons.

I am using the following script to remove sections manually and adding it back to sortable-sections, but it is not registering the jquery events.

 var $section = $('.sortable-sections').find($('#flSectionType');
 $('.sortable-sections').find($('#flSectionType').remove();
 ......
 .......
 $('.sortable-sections').append($section.val());

After appending the section, the event which are registered for the section-add-item css classes are not triggering.
Note:
instead of “on” used the “live” method. but it is not holding all attributes.

Edit:
Event code:

   $('.section-add-item').on('click', function (e) {
        that.addSection(this);
        e.preventDefault();
    });

instead of drag and drop, manually i am ordering the section on initial load.

Answer 1

.section-add-item must already exist when adding the event and the usage of on is wrong

$('body').on('click', '.section-add-item', function (e) {

});

instead of the body you can add another parent of .section-add-item that already exists before .section-add-item is created.
