update() loses associated tmplData

[warappa]

When a template element is updated, the data associated with the element is lost (more specific: the whole jQuery data object is lost).

$(this).tmplItem().data; // returns associated model fragment
// manipulate data
$(this).tmplItem().update(); // update renderes template with the updated data
// data gets rendered correctly
$(this).tmplItem().data; // data is empty!

Result: Data is empty.

Expected: Data should be preserved.

update renders the template, so the element this will be removed from the DOM when you call update. Therefore $(this).tmplItem() will not be what you want on the next line.

var item = $(this).tmplItem()
item.data; // returns associated model fragment
// manipulate data
item.update(); // update renderes template with the updated data
// data gets rendered correctly
var test = item.data; // data is not empty!
