Add a value in Datalist using Jquery

In a scenario there is a Datalist and there are some Datalist values in that Datalist. When you will click on any Datalist value that value will be invisible from that Datalist and should be shown on vf page with a checkbox and when you will check that checkbox that value will be invisible from page and again should be shown in datalist. I want to solve this problem using JQuery. I have gone through following code but not getting complete solution. Can i get any solution..?

function checkboxClick(obj){
var id = $(obj).attr("id");
if($('#' + id).is(":checked")){
$(obj).closest("tr").remove();
}
}
$(document).ready(function(){
var a;
var idCounter=1;
$(document).on('click', '#ddlList', function () {
a = $('#ddlList option:selected').text();
$('#ddlList option:selected').remove();
if(a != ''){
var b = $('#demo').append('

<tr>

<td><input type="checkbox" onclick="checkboxClick(this)" id="ck_'+idCounter+'"/></td>

<td class="newLine">'+a+'</td>

</tr>

');
idCounter++;
}
});
});

----------------------

<select id="ddlList">
<option value="0">None</option>
<option value="1">ASP.NET</option>
<option value="2">C#</option>
<option value="3">VB.NET</option>
<option value="4">HTML</option>
<option value="5">jQuery</option>
</select>
<table id="demo">
<tbody>
<tr>
<td></td>
</tr>
</tbody>
