Elasticsearch: Auto delition with ILM doesn't work - elasticsearch

Question

I wanna delete an index after certain time(say 10s) but it doesn't work. I researched a lot but I couldn't find a different thing from my configs. Here are my configs:
my ILM config:
{
"policy": {
"phases": {
"hot": {
"min_age": "0ms",
"actions": {
"set_priority": {
"priority": 100
}
}
},
"delete": {
"min_age": "10s",
"actions": {
"delete": {}
}
}
}
}
}
my template:
{
"order": 0,
"index_patterns": ["myindex.*"],
"settings": {
"index": {
"lifecycle": {
"name": "myindex"
}
}
}
}
my index:
{
"job_id": 1,
"message": "sample data",
"#timestamp": "DATETIME"
}
then with the following script, I test my scenario:
#!/bin/bash
NAME=myindex
# Add ILM and template.
echo -n "Add policy..."
http PUT http://localhost:9200/_ilm/policy/"${NAME}" < ilm.json
echo -n "Add template..."
http PUT http://localhost:9200/_template/"${NAME}" < template.json
# Create index.
echo -n "Create index..."
http PUT http://localhost:9200/"${NAME}" | jq '.acknowledged'
# List of data stream and indices.
echo -n "List of data stream..."
http http://localhost:9200/_data_stream/ | jq '.data_streams'
echo "List of indices..."
http http://localhost:9200/_cat/indices/ | awk '{print $3}'
echo "Index ILM explain..."
http http://localhost:9200/"${NAME}"/_ilm/explain
# Insert a document.
echo -n "Insert a document..."
sed "s/DATETIME/$(date +%Y-%m-%dT%H:%M:%S)/g" < index.json | http POST http://localhost:9200/"${NAME}"/_doc | jq -r ".result"
# Wait until it reaches the TTL.
echo "Waiting to reach the TTL..."
sleep 10 # "$(( $(jq -r .policy.phases.delete.min_age < ilm.json | sed 's/s//g') + 2 ))"
# Search for the data and expected to find nothing.
echo "Search the inserted document..."
echo '{"query": {"match": {"job_id": 1}}}' | http http://localhost:9200/"${NAME}"/_search
In the last part when I search for the index I can find it. The index is still present!!!

I set indices.lifecycle.poll_interval and it works!
PUT /_cluster/settings
{
"persistent" : {
"indices.lifecycle.poll_interval": "5s"
}
}
