Show real time log with Laravel 5.3 while executing bash script

I have a bash script that is execute in a function in a laravel Controller and I want to output the echos from within while the script is being executed. I tried this way but it does not work, it shows everything togheter after the script is executed.

public function execute_bash(command)
    {
        flush();
        $fp = popen(command, "r");
        while(!feof($fp))
        {
            // send the current file part to the browser
            print fread($fp, 1024);
            // flush the content to the browser
            flush();
        }
        fclose($fp);

    }

I do that with ajax

$.ajax({
        data:  parameters,
        url:   '/executeBash',
        type:  'get',
        beforeSend: function(){
            console.log("executing...");
        },
        success:  function(response){
            console.log("success: %O", response);
        },
        error:  function(response){
            console.log("error: %O", response);
        }
    });

How can I achieve wath I want? Thanks!
