How to select drop downs inside any div?

Question

I am using ExtJs with Jquery. I have a panel under which I have check boxes, radios and drop downs. I am using the following code to get all the items under the panel.

    $('#panelId : input').each

This works for radio and check boxes. But, I am trying the following for drop down and it is not working

    $('#panelId : select').each

Experts please guide me.

Note: I am painting raw html into the panel using XTemplate. So I am not able to retrieve the items using extjs (Rather I don't know!). Can any one suggest the same using extjs?
