mvc Get a value of element in different cshtml with jquery - asp.net-mvc

Question

I have a page ("mypage.cshtml") and two partial view page ( partial1.cshtml, partial2.cshtml )
when Im in mypage click a button and display a modal which call partial1 with #Html.Partial("patial1") in a modal(bootstrap modal). it consist of html. when I a click a button on this modal it calls another modal consist of partial2..
Here is the issue; When I load the page begining (in mypage ) I need to get the value of checkbox that standing in second modal, that is partial2.
During I view this modal I can get this value with this:
$("input[type='checkbox'][id='4']").val();
it gives me the value which I expect but at the begining(in mypage.cshtml) this returns "undefined" :S
I couldnt understand this stuation both of these modal located in mypage but why I cant get these elements values untill I reach them ?
here is view mypage:

Answer 1

Since you load your partial trough a modal, I'm assuming that the actual loading is done using AJAX. This means that when you first load your HTML page (the initial one), the partial is not yet part of the DOM (might have not been requested from the server). This in turn means that you checkbox is also not part of the DOM, and therefore is returned as undefined.
