I tried some of the proposed above methods. However, no one was useful to me. After looking some information, I found the property attribute in jQuery (prop()). And that one works for me, the code is the following:

In my JSF file, I had the following code. 

<h:selectOneMenu id="asignacion" value="#{contratosBean.asignacion}">
<f:selectItems value="#{contratosController.asignaciones}"
        var="item" itemLabel="#{item.lblAsignacion}"
        itemValue="#{item.idAsignacion}" />
<f:ajax onevent="showDialog()" />

JavaScript section:

function showDialog() { if($([id='formContrato:asignacion']").prop("selected",true).val() == 'X1') { alert("function X1"); }else if($("id='formContrato:asignacion']").prop("selected",true).val() == 'X2'){alert("function X2"); }else{alert("Other function");} }

Concatenate like this:

var atLeastOneIsChecked = jQuery('input[name="addon-'+abc+'"]:checked').length ;

var atLeastOneIsChecked = jQuery('input[name="addon-"'+abc+']:checked').length;
                                                    ^
                                                    |

You used the closing " at the wrong place

var atLeastOneIsChecked = jQuery('input[name="addon-'+abc+'"]:checked').length;
                                                           ^
                                                           |

Try this - 

var atLeastOneIsChecked = jQuery("input[name='addon-"+abc+"']:checked").length ;
