model view controller - I cannot get the Telerik MVC extensions grid to show a total with ClientFooterTemplate -

i using ajax binding , assuming if want total update after user edits change, need clientfootertemplate opposed footertemplate works.

here grid works footertemplate:

    @{     grideditmode mode = (grideditmode)viewdata["mode"];     gridbuttontype type = (gridbuttontype)viewdata["type"];     gridinsertrowposition insertrowposition = (gridinsertrowposition)viewdata["insertrowposition"];     html.telerik().grid<redfile.models.quickquoteitemview>("items")         .name("quoteitems")         .datakeys(k => k.add(o => o.id))         .toolbar(commands => commands.insert().buttontype(type).imagehtmlattributes(new { style = "margin-left:0" }))         .columns(c =>         {             c.bound(o => o.id).readonly().hidden();             c.bound(o => o.itemid);             c.bound(o => o.description);             c.bound(o => o.itemqty);             c.bound(o => o.itemprice).format("{0:c}");             c.bound(o => o.linetotal)                 .width(100)                 .aggregate(ag => ag.sum())                 .footertemplate(result => (result.sum == null ? "0.00" : result.sum.format("{0:c}")))                 .format("{0:c}");             c.command(s =>             {                 s.edit();                 s.delete();             });         })         .editable(editing => editing.mode(mode).insertrowposition(insertrowposition))         .databinding(b => b.ajax()             .select("gridselect", "quickquote")             .insert("gridinsert", "quickquote", new { qqid = model.id })             .update("gridupdate", "quickquote", new { qqid = model.id })             .delete("griddelete", "quickquote", new { qqid = model.id })             )         .footer(true)         .render(); } 

if change footer template this: (i have tried multiple variations same result)

                .clientfootertemplate("<#= $.telerik.formatstring('{0:c}', sum) #>") 

the total disappears.

all want total updates after user changes something. idea i'm doing wrong?

thanks

columns.bound(p => p.itemprice)                     .footertemplate(                         @<text>                             total:@string.format("{0:c}", model.itemprice)                         </text>                     )                     .width(100)                     .format("{0:c}");
