JQuery unrecognized expression in parsing MVC Partial

This is a quick tip sharing. Recently, I was stuck in a problem where I was making an AJAX call to get MVC partial as HTML in response.

Within this response, I made an attempt to find an element using $.find as following:

$.ajax({
   url: theURL,
   type: "POST",
   success: function (data) {
                 var controls = $(data).find('#someTextBox'); }
});
