Help with ajax not get script error in IE9

Help with ajax not get script error in IE9

Good morning everyone,
I have a problem when making a request by ajax.
I'm using the $. ajax () this function and returns the search results in Firefox and Chrome more in IE9 it just returns the HTML and plays in the div I want it to handle and runs a <script> </ script> other the page you're doing the request! Remembering that everything is ok in chrome and firefox only in IE9 only loads the HTML, not the script.
