Instantiate contract from clone factory with value

Question

I'm currently trying to create instances of a smart contract via a clone factory. The problem is, that I'm not able to send a value to the init function of the smart contract I'm trying to instantiate. Here is a example:

TestContract.sol

// SPDX-License-Identifier: MIT
pragma solidity >0.4.23 <0.9.0;
contract TestContract {
    string testmessage;
function init(
    string memory _testmessage
) public payable {
    require(msg.value > 0, "The contract has to have at least a value");
    testmessage = _testmessage;
}

TestContractFactory.sol

// SPDX-License-Identifier: MIT
pragma solidity >0.4.23 <0.9.0;
import "./TestContract.sol";
import "./CloneFactory.sol";
contract TestContractFactory is CloneFactory {
    address public testContractAddress;
    address[] public clonedTestContracts;
event TestContractCreated(address newTestContract);
constructor(address _testContractAddress)
{
    testContractAddress = _testContractAddress;
}
function createTestContractAddress(
    string memory testmessage
) public payable {
    address clone = createClone(testContractAddress);
    TestContract(clone).init(testmessage);
    clonedTestContracts.push(clone);
    emit TestContractCreated(clone);
}

}

So when I try to instantiate a TestContract via the Factory in Remix with the value of 1 Ether, I get the message "The contract has to have at least a value". Does someone know why this happens? I was only able to find examples that use normal factories and not clone factories.
