unable to submit two values separtely

[nikhil_me]

hi!!
i am using the code
<h:inputText id="userid" value="#{issuetoTO.id}" onchange="sumbit();" ></h:inputText>
to set the value of issuetoTO.id and it is running fine but when i add
<h:inputText id="username" value="#{issuetoTO.name}" onchange="sumbit();" ></h:inputText>
none of the two values are being set????
can't I use submit twice in a single form???
