    // the button
    $("#client").live("click", function(){
       alert('test'); 
    });

   // the input text
   $("#pesq_model").live("keypress", function(e){
       // testing with nothing 
   });

Answer 1

IE treats button tags in a special way. You could use an input instead of a button:

<input type="button" style="border: solid #dedede 2px; width:130px;" id="client" value="Trocar Cliente" />
