<div class="row text-center" >
<div  style="width:30%;"  id="cblist" ></div>

</div>

<input type="button" value="AddCheckbox" id="btnSave" />

<script type="text/javascript">
$(document).ready(function() {
    $('#btnSave').click(function() {
        addCheckbox();
    });
});

function addCheckbox(name) {
   var container = $('#cblist');
   var inputs = container.find('input');
   var id = inputs.length+1;
   $('<input/>', { type: 'checkbox', id: 'cb'+id, value: 'cb'+id,class:'col-xs-4'}).text('hsssello').appendTo(container);     
   $('<label />', { 'for': 'cb'+id, text: 'label'+id, class:'col-xs-8' }).appendTo(container);
