Sorting a gridview with unbound column (i.e autogeneratecolumns="false")

GridControl

I already have a table in place where I have set the autogeneratedcolumns to false and allowsorting to true. Furthermore, I have an event created onsorting, now when I run, the header links are not clickable like the ones you have when autogeneratedcolumns is set to true. Hence the event onsorting is not getting triggered.

What I have tried:

AllowPaging="True"
                   PageSize="20"
                   CssClass="mGrid"
                   AllowSorting="True"
                   OnSorting="propertySearchDataGrid_Sorting"
                   PagerStyle-CssClass="pgr"
                   AlternatingRowStyle-CssClass="alt"
                    AutoGenerateColumns="False"

My settings are as above.
