jQuery data() from a function

I set jQuery object's data using a function: 

oTabSearch.data('search_data', collect_data());

Is there a way to somehow recalculate this data piece e.g. if I get data from object:

var search_data = oTabSearch.data('search_data');

it would first set 'search_data' data using collect_data() function and then return it?

You can do this...

oTabSearch.data('search_data', collect_data);  // notice no parenthesis

and to run the function...

var search_data = oTabSearch.data('search_data')();  // notice the empty parenthesis

That effectively stores a copy of the function as a data object and then runs it again when you request. It does not store any return value.

Here's an example jsFiddle...

Click "mydiv" to see the data value, therefore calling the function again.
