It's sound like easy but I can't do that.

Could you please advice? Thank you.
<div id="Div1">
</div>
<a href="javascript:void(0)" class="easyui-linkbutton" data-options="iconCls:'icon-add'" onclick="addPanel()">Add Panel</a>
<script>
function addPanel() {
var pp = $('#pp').panel({
width: 500,
height: 150,
title: 'My Panel',
tools: [{
iconCls: 'icon-add',
handler: function() { alert('new') }
}, {
iconCls: 'icon-save',
handler: function() { alert('save') }
}]
});
$("#Div1").append(pp);
}
</script>
