ASP.net Adding new Button to GridView give an error in jquery.dataTables.min.js

I currently have a GridView and I'm trying to add a button. I'm able to add it but when I click on it I get this weird error on this line.

if(c.mData===a){var d=u(b,"sort")||u(b,"order"),e=u(b,"filter")||u(b,"search");

Error:

Unhandled exception at line 91, column 426 in http://localhost:23549/Scripts/jquery.dataTables.min.js

0x800a138f - Microsoft JScript runtime error: 'mData' is null or not an object

I've done a bit of research and I can't find this issue anywhere else. Other users are getting the same error but none of them use ASP. I tried changing some properties on the button. I also tried adding it has a ButtonField instead but I still get the same error.

<div class="datatable">
    <asp:GridView runat="server" ID="jobGridView" AutoGenerateColumns="False" BorderWidth="0px" GridLines="None" CssClass="table table-hover table-condensed font13" OnRowDataBound="jobGridView_RowDataBound" DataKeyNames="site_id,id" OnRowCommand="OnOff">
        <Columns>
            <asp:BoundField DataField="site_id" meta:resourcekey="siteField" />
            <asp:BoundField DataField="id" meta:resourcekey="jobNameField" />
            <asp:BoundField DataField="job_start_date" meta:resourcekey="jobStartField" DataFormatString="{0:yyyy-MM-dd HH:mm:ss}" />
            <asp:BoundField DataField="job_end_date" meta:resourcekey="jobEndField" DataFormatString="{0:yyyy-MM-dd HH:mm:ss}" />
            <asp:BoundField DataField="job_duration" meta:resourcekey="jobDurationField" DataFormatString="{0:HH:mm:ss.fff}" />

            <asp:BoundField DataField="job_last_failure" meta:resourcekey="jobLastFailureField" DataFormatString="{0:yyyy-MM-dd HH:mm:ss}" />
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:LinkButton ID="lnkSelect" runat="server" Text="View" OnClientClick='<%# GetOpenTabJavascript(DataBinder.Eval(Container.DataItem, "id"), DataBinder.Eval(Container.DataItem, "site_id"))%>' />
                </ItemTemplate>
            </asp:TemplateField>
             <asp:TemplateField>
                <ItemTemplate>
                    <asp:Button ID="Button1" runat="server" CommandName="OnOff" Text="Turn On/Off" ShowHeader="True" CommandArgument='<%# Eval("id") %>' />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</div>

 protected void OnOff(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "OnOff")
            {
               //This part gets hit when debugging, error is after
            }

        }

If I remove the button everything works fine. (The LinkButton work)

I tried changing the type of event to RowEditing and RowUpdating. Same error.

Where should I start debugging to find out where the error comes from? Feel free to ask any questions.

The error is being pretty straightforward in just letting you know jquery.dataTables is looking for an object named mData which is currently null and/or false.

Try giving your <div class="datatable"> an ID to match what dataTables is looking for.

That is, <div class="datatable" id="mData"> I'm not 100% sure that will do it, but your solution will be definitely in the neighborhood.

I've used dataTables a lot and tended to run into lots of annoying errors like this that just took debugging and banging my head on the desk some before I figured it out.

Seems like otherwise (can't really tell without debugging myself) your code would be fine--you just need to explicitly tell dataTables what mData is. If it's not on the <div>, maybe the button or GridView: honestly, too many variables for me to know for sure (unless you try some of these and have feedback! :))
