CFGRIDCOLUMN not accepting type="date" in CF8

I recently coded a CFGRID using CF9 with date fields using type="date". The date fields appear nicely with a little calendar to the right of the cell. I now realize that I have to have this working on a CF8 server. Is there any fix or addition that I can code to implement this calendar feature in CF8?

  <cfgrid  

                name="taskGrid"

                bind="cfc:QuestionsDAO.GetEmployeeGroupObjectiveQuestions({cfgridpage }, {cfgridpagesize}, {cfgridsortcolumn}, {cfgridsortdirection},#employeeID#,{groupID},{scaleName})"

                gridlines="yes"

                colheaderalign="center"

                colheaders="yes"

                format="html"

                align="middle"

                width="1200"

                colheadertextcolor="blue"

                style="border: groove 3px black"

                striperows="true"

                striperowcolor="##CAE4FF"

                autowidth="yes"

                title="Task List for #getPOname.poname# as of #DateFormat(now(), 'mm/dd/yyyy')#"

                collapsible="true"

                pagesize="30"

                selectmode="edit"

                onchange="cfc:QuestionsDAO.saveObjectiveDates({cfgridaction}, {cfgridrow}, {cfgridchanged},{scaleName})"

                onerror="catchGridError"

            >

        <cfgridcolumn name="EmpObjID" header="Employee Objective ID"  display="no" />       

        <cfgridcolumn name="qid" header="QuestionID" select="false"  display="no" />

        <cfgridcolumn name="qtext" header="Question"  select="false" width="400"/>

        <cfgridcolumn name="ScaleCompletedDate" header="Date" type="date" mask="m/d/y" width="100"/>

        <cfgridcolumn name="Completed" header="Completed" type="boolean" width="100" />

      </cfgrid>

Thanks!
