Find and replace a content which is inside Content Control-docx4j - docx4j

Question

I tried to replace a text using docx4j. As a first step I've applied bookmark for the texts which are need to replace. Using bookmark i'll find the text and replace it. This is working fine. I have a replace problem when the bookmarked content is inside a Content control.Can anyone help me out. Thanks in advance.
For example in the below Sample input, If CTBookmark value equals of "replacetext_1_0" which is inside a Content Control then I need to insert the replace value.
Code Snippet:
private void replaceViaBookmarkWithTrack(P p, ObjectFactory factory, String search, String replace, String replaceBkName) throws JAXBException {
List<Object> pContents = p.getContent();
int rIndex = 0;
int runCount=0;
int c = 0;
boolean delete = false;
List<Object> deletes = new ArrayList<Object>();
BigInteger start = null;
int startValue = -1;
RunIns runIns = factory.createRunIns();
RunDel runDel = factory.createRunDel();
for (Object run : pContents) {
Object temp = run;
if (temp instanceof JAXBElement) {
temp = ((JAXBElement<?>) temp).getValue();
}
// if(temp instanceof SdtContentBlock){
// logger.info("Content Control here");
// }
if (temp instanceof CTBookmark) {
if (((CTBookmark) temp).getName().contains(replaceBkName)) {
start = ((CTBookmark) temp).getId();
startValue = start.intValue();
if (c == 0) {
runDel.setAuthor("Auto Process");
runDel.setDate(xmlDate);
runIns.setAuthor("Auto Process");
runIns.setDate(xmlDate);
R newDelRun = factory.createR();
R newInsRun = factory.createR();
DelText deltext = factory.createDelText();
deltext.setSpace("preserve");
deltext.setValue(search);
newDelRun.getContent().add(deltext);
runDel.getCustomXmlOrSmartTagOrSdt().add(newDelRun);
Text t = factory.createText();
t.setSpace("preserve");
t.setValue(replace);
newInsRun.getContent().add(t);
runIns.getCustomXmlOrSmartTagOrSdt().add(newInsRun);
rIndex=runCount;
c++;
delete=true;
}
}
} else if (temp instanceof CTMarkupRange) {
if (((CTMarkupRange) temp).getId().intValue() == startValue) {
deletes.add(run);
delete = false;
}
}
if (delete) {
deletes.add(run);
}
runCount++;
}
for (Object o : deletes) {
p.getContent().remove(o);
}
p.getContent().add(rIndex, runIns);
p.getContent().add(rIndex, runDel);
}
