TinyFCK not inserting image URL once image selected

I see "result" is showing path of the image properly and in target I see src which is textbox name where path has to insert.

Problem is path is not inserting meaning in the src id textbox. Meaning target.value = result; is not working. Anyone tell me whats wrong please?

    if (enableAutoTypeSelection && cType) {
        connector += "&Type=" + cType;
    }

    window.open(connector, "tinyfck", "modal,width=600,height=400");
