hi,
through the
onChangingValuescallback you can obtain the dom node of the updateing row (that is a clone of the template) as it is passed as the second parameter in the call, or, if
setPushedHtmlEnabled is set to true, inject your html as the formatted value of one of the field (you could use a client-side field for this purpose with the
addField method but note that setPushedHtmlEnabled must be true anyway for the entire table)
