I can’t really see what this offers that the JQuery UI’s built in dialog doesn’t…

Hi, it is a nice and neat plug-in but I have some problem.
Here is how I use it in my page :

$(document).ready(function () {
$(’.ResponseLink’).live(’click’,function () {
var idval = this.id;
$.ajax({
url: “/Admin/Contact/Edit”,
data: { id: idval },
dataType: ‘html’,
success: function (mydata) {
$(”#ContactArea”).empty().append(mydata);
},
type: “GET”
});
return false;
});

$(’.RemoveLink’).live(’click’, function (e) {
e.preventDefault();

//var elem = $(this).closest(’.item’);

$.confirm({
‘title’: ‘Delete Confirmation’,
‘message’: ‘You are about to delete this item. It cannot be restored at a later time! Continue?’,
‘buttons’: {
‘Yes’: {
‘class’: ‘blue’,
‘action’: function () {
//elem.slideUp();
}
},
‘No’: {
‘class’: ‘gray’,
‘action’: function () { } // Nothing to do in this case. You can as well omit the action property.
}
}
});
});
});

When page loads and I click on RemoveLink it shows confirmation dialog, but after clicking on ResponseLink, if I click on RemoveLink again, the fire-bug console shows this error : $.confirm is not a function

Would you help me please ?
