grid.common.js failes trying to evaluate custom_element

                    if($.isFunction(options.custom_element)) {

Please call eval in the next block

                    } else {
                        celm = eval(options.custom_element)(this,vl,options);
                        //throw "e1";
                    }

the same error in grid.inlinedit.js and grid.celledit.js for

editoptions.custom_value

custom_element has three parameters (this,vl,options)
