在单选按钮中调用javascript无法正常工作

Question

我在点击单选按钮时调用java脚本函数，并根据单选按钮我需要调用另一个java脚本函数来清除一些字段值。

问题：始终输入批准功能和字段未清除

这里是代码的快照，请仔细阅读并指导我在哪里错了，可以做些什么。

<h:selectOneRadio id="selectApprovaRl1" onfocus="return setemptyrejquery(this.form)" value="#{bean.approvalCode}"> <f:selectItem id="selDecR1" itemLabel="Approve" itemValue="Approved" /> <f:selectItem id="selDecR2" itemLabel="Reject" itemValue="Rejected" /> <f:selectItem id="selDecR3" itemLabel="Query" itemValue="Queried" /> <f:selectItem id="selDecR4" itemLabel="Pending" itemValue="Pending" /> <a4j:support event="onclick" reRender="listPanel11,listPanel22,listPanel33,listPanel44,listPanel445" /> </h:selectOneRadio>   

java脚本函数

<script type="text/javascript">
    function setemptyrejquery(f){
        alert("running................."+f.name);

        var ex1 = document.getElementById('selDecR1');
        var ex2 = document.getElementById('selDecR2');
        var ex3 = document.getElementById('selDecR3');
        var ex4 = document.getElementById('selDecR4');

        ex1.onclick = approve(f.name);
        ex2.onclick = rejquery(f.name);
        ex3.onclick = rejquery(f.name);
        ex4.onclick = pending(f.name);

    }
        function approve(f) {
            alert("running.......approve.........."+f);
        var txt4=document.getElementById('textDec12').value="";
        var txt5=document.getElementById('textDec2').value="";
        alert("Reseted........approve");
    }

        function rejquery(f) {
            alert("running.......rejquery.........."+f);
        var txt4=document.getElementById('textDec1').value="";
        var txt5=document.getElementById('textDec22').value="";
        alert("Reseted.........rejquery");
    }

        function pending(f) {
            alert("running.......pending.........."+f);
        var txt4=document.getElementById('textDec145').value="";
        var txt5=document.getElementById('textDec2245').value="";
        alert("Reseted............pending");
    }
</script>

html生成

<table class="form-container" width="100%">
  <tbody>
    <tr>
      <td class="col_label">
        <span id="Form:decision">
