Unfortunately i'm not at work so i can't get the actual code. However, I accomplished this by writing the javascript event as an html attribute in the Controller, then passed it along in the ViewData.

When you write the code:

<%=Html.DropDownList("SelectList", (SelectList)ViewData["SelectList"], [htmlAttribute])

Basically in the Controller you would write the htmlattribute and assign it in the dropdownlist method.

I know this is an old post, but I found a link that shows a workaround where you can keep the same name for the dropdown list and keep data binding for the model on the form post:

I think this is a huge bug and am surprised it's not been fixed yet. Anyways, I hope this helps.

Found the Answer

When the Name given to the control (the first parameter in this case being "SelectList") is the same as one of the Keys in the ViewData dictionary basically it screws up and ignores the pre-selected item in the SelectList

By simply renaming the DropDownList it works correctly and binds to the Pre-Selected item
