Datatable cellEditor functionality in forEach generated Datatable - foreach

Question

I am trying to generate a editable datatable dynamically dependend on the resultset of an previously executed SQL-Query.
Depending on which columns would have a constant value I am trying to not render them. That part of the code works just fine, everything is displayed as i would like it to be.
My issues are with the cellEditor. I generate my datable as follows:
<p:dataTable ajax="true" var="mBT" value="#{stammdaten.bbvList}" id="meldeBearbeitungsTable" editable="true" editMode="cell" scrollable="true" scrollHeight="400" style="width:600px">
<p:ajax event="cellEdit" listener="#{stammdaten.onCellEdit}" update=":Mb:message"/>
<c:forEach var="column" items="#{stammdaten.columns}">
<p:column headerText="#{column.header}">
<f:attribute name="myCol" value="#{column}" />
<span>
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{mBT[column.property]}"></h:outputText>
</f:facet>
<f:facet name="input">
<p:inputText value="#{mBT[column.property]}">
<p:keyFilter regEx="/[0-9]/i"/>
</p:inputText>
</f:facet>
</p:cellEditor>
</span>
</p:column>
</c:forEach>
</p:dataTable>
bbvList is a List of beans with different values.
columns is a List of beans to identify the header-Texts coresponding to the respective variables.
So now the issue itself:
This is how the cellEditor looks like when i click on it:
Issue-Picture
So in that example i tried to edit the field with the value "8" in it. onCellEdit gets triggered (a System.out.println is getting printed on the console) but i cant actually change the value in the respective field.
Does have cellEdit issues with the forEach initialisition of the dataTable? If yes is there a way to fix it? Else what am i doing wrong?
Since only a specific component of the html-side of code isnt working as it should be i won't post unnecessary java-Code for now. If needed i will add that as well.
Hope someone can help :)

Turns out the attribute and/or span where the cause of the problem. Simply removing them solved the issue with the cellEdit.
following works fine :
<p:dataTable ajax="true" var="mBT" value="#{stammdaten.bbvList}" id="meldeBearbeitungsTable" editable="true" editMode="cell" scrollable="true" scrollHeight="400" style="width:600px">
<p:ajax event="cellEdit" listener="#{stammdaten.onCellEdit}" update=":Mb:message"/>
<c:forEach var="column" items="#{stammdaten.columns}">
<p:column headerText="#{column.header}">
<p:cellEditor>
<f:facet name="output">
<h:outputText value="#{mBT[column.property]}"></h:outputText>
</f:facet>
<f:facet name="input">
<p:inputText value="#{mBT[column.property]}">
<p:keyFilter regEx="/[0-9]/i"/>
</p:inputText>
</f:facet>
</p:cellEditor>
</p:column>
</c:forEach>
</p:dataTable>
