what ive figured out loop through option values , change them echoing javascript code , works getting values , changing state of select form. wanted echo onchange(); doesnt work. how can force onchange() on select form through php echoing javascript code?

i tried 

echo '<script type="text/javascript">     var select = document.getelementbyid("group_1");             var option = select.getelementsbytagname("option");     for(j=0; j < option.length; j++){         option[j].removeattribute("selected");     }     option['.$i.'].setattribute("selected","selected");     select.onchange();  </script>';

which works in console not echoing php
