defect reopen count using dojo scripting calculated value

Hi, the following is the DOJO script to calculate the defect reopen counter, basically when ever the defect fails during testing it will be reopened, and the counter should increment by 1. Dont have a clue why the counter is incrementing twice when the defect is reopened, any idea appreciated. so this script gets executed whenever the status is changed.

dojo.provide("defectopencounter");
dojo.require("com.ibm.team.workitem.api.common.WorkItemAttributes");
(function() {
var WorkItemAttributes = com.ibm.team.workitem.api.common.WorkItemAttributes;
dojo.declare("defectopencounter", null, {
    getValue: function(attributeId, workItem, configuration) {
    var defectcount = parseInt(workItem.getValue("defectopencounter"));
        var stat = workItem.getValue(WorkItemAttributes.STATE);
        var act=configuration.getWorkflowAction();
        if(stat === "1")
            {   
                console.log("yes status is Open");
                console.log("the current count value:" + defectcount);
                defectcount = defectcount+1;
                console.log("the current count value after addition:" + defectcount);
            }
                return parseInt(defectcount);
    }
});
})();
