Remove item from list using jquery

I have been working all day on one of my first javascripts which is designed to have a user insert items into a text box using a field and submit button. Items that are put in the list have a remove button next to them.

I was wondering if anyone had any smart ideas about how I could remove items using the remove link next to the list. When this link is clicked I want to have it removed from the list but I can't really see a clean and simple way of doing it.

Demo Jsfiddle: http://jsfiddle.net/spadez/ZTuDJ/46/

// If JS enabled, disable main input
$("#responsibilities").prop('disabled', true);
// $("#responsibilities").addClass("hidden");

// If JS enabled then add fields
$("#resp").append('<input placeholder="Add responsibility" id="resp_input" ></input><input type="button" value="Add" id="add"> ');

// Add items to input field
var eachline='';
$("#add").click(function(){
    var lines = $('#resp_input').val().split('\n');
    var lines2 = $('#responsibilities').val().split('\n');
    if(lines2.length>10)return false;
    for(var i = 0;i < lines.length;i++){
        if(lines[i]!='' && i+lines2.length<11){
        eachline += lines[i] + '\n';
        }    
    }

    $('#responsibilities').text($("<div>" + eachline + "</div>").text()).before("<li>"+$("<p>"+lines+"</p>").text()+"<span class='right'><a href='#'>Remove</a></span></li>");

    $('#resp_input').val('');
});

I know people have much more experience, so if anyone is willing to give me any help or advice on how this could be achieved I would really apprecaite it.

Really simple : 

$(document).on('click', '.right a', function(){
    $(this).closest('li').remove()
})

Fiddle : http://jsfiddle.net/ZTuDJ/47/

To remove the textarea too, use this:

$(document).on('click', '.right a', function(){
    var el = $(this).closest('li')
    var index = $('li').index(el);
    var text = eachline.split('\n');
    text.splice(index, 1);
    eachline = text.join('\n')
    $('#responsibilities').text(eachline)
    el.remove()
})

Something like this?:

$("ul li a").on("click", function(){
    $(this).parent().remove();
});

JSFiddle here
