jQuery UI Dialogs

jQuery UI Dialogs

This is what I am trying to build
1) Trying to integrate jQuery UI Dialogs into my application 
Effort is to open different html views into the same dialog based on a click on different href links.

Enclosing a small snippet 
a) This is the container
    <!--Start : report Dialog Container-->
    <div id="reportDialog" style="display:none;">
        <iframe frameborder="0" scrolling="no"></iframe>
    </div>

b) To open a dialog
 var open = function (reportId, description) {

 var opt = {
                autoOpen: false,
                modal: true,
                resizable: false,
                width: 650,
                height: 650,
                title: description
            };
            var theDialog = $("#reportDialog").dialog(opt);
                $('#reportDialog').load('/app/components/reports/' + reportId + 'View.html', function () {
                $(this).dialog('open');
            });

The problem that I am facing currently is trying to use third party controls like sumoSelect to be applied to a SELECT  element. This would be controls loaded in the individual reports in the dialog. The issue here is the 
$('.SlectBox').SumoSelect({ csvDispCount: 3 }); should be executed after the html content is loaded in the jquery ui dialog , else it wont work. 

 <select name="curAsOfDate" class="SlectBox">
                        <option value="1">Q1 2015</option>
                        <option value="2" selected="selected">Q4 2014</option>
                        <option value="3">Q3 2014</option>
                        <option value="4">Q2 2014</option>
                        <option value="5">Q1 2014</option>
                    </select>

$('.SlectBox').SumoSelect({ csvDispCount: 3 });
