I am trying to refer to a component using document.getElementById which is includede by apex:insert tag. The problem is I am not having control over specifying Id for the Insert tag, which salesforce assigns randomly when page renders.

Below is the sample code, I am not able to get reference of  "idLabelTag".

    <apex:insert name="header">
            <c:BIBheader />
    </apex:insert>

<apex:component id="BIBheader">

        <apex:outputLabel  id="idLabelTag" >800 888 1111</apex:outputLabel>

</apex:component>

Is there something I can do to fix this?
