Rendering JSP in ALLOY DIALOG

Question

Hi

I am using ALLOY DIALOG in Liferay 6.0.5 as follows:

function countPopup(){

AUI().use('aui-dialog', 'liferay-portlet-url', function(A) {

        var dialog = new A.Dialog({
        title: 'Upload Details',
        centered: true,
        modal: true,
        width: 500,
        height: 400,
        bodyContent:"testing",

        }).render();

    });

}

I am getting in popup " testing ". But Instead of "bodycontent" I want to forward to one jsp file where i have written some logic. How to do that?
