Add dropdown box to html table using javascript help

I have a custom javascript handler that when a button is pressed it appends a row to a html table like so:

 $(table).append(
            '<tr><td><input  class="SettingsListField save_pending" type="text" ' +
            'id="' + $(this).attr('id') + '_' + newIndex + '" name="' + $(this).attr('id') + '"></td>'+
            '<td><input  class="SettingsListField save_pending" type="text" ' +
            'id="' + $(this).attr('id') + '_' + newIndex + '" name="' + $(this).attr('id') + '"></td>'+
            '<td><div class="SettingsIconContainer"><a class="InputListbtnRemove" onclick="return false;">'+
            '<img src="/static_media/img/RemoveButton2_small.png" alt="Remove address details" /></a></div></td>'+
            '<td><div class="SettingsStatusContainer" id="' + $(this).attr('id') + '_' + newIndex + '_status"></div></td>'+
            '</tr>'
            ); 

Select allOpen in new window

This is working fine.

Now I want to modify this so that adds a dropdown box and adds some items to this dropdown box.

SO I have added the following line

 '<td><select class="CustomSelect1 not_changed" id="' + $(this).attr('id') + '_' + newIndex + '" name="' + $(this).attr('id') + '" <option>"item1"</option>></td>'+

Select allOpen in new window

Now this adds the dropdown box but it does not iinsert the "item1" into it??

What am I doing wrong??

Thanks
