Knockoutjs: Expanding the SimpleGrid to Support Sorting

How would you modify the kno开发者_如何学Cckout.js simpleGrid plug-in to support column sorting?

I have got the following code: http://jsfiddle.net/NaveenVelaga/QSRBR/9/

Use KnockoutSimpleSortableGrid found at https://shiljopaulson.github.io/Knockout.simpleSortableGrid/ and it contains samples in it

I have had a fiddle with the supplied code.

I have modified the simpleGrid code to expect a sorting function in the column data. This way we can wire up the template to sort on click via the supplied function.

This is a simple solution which needs to be expanded to include bi directional sorting logic (second click sorts in reverse direction)
