I have attached a keypress event to my textbox. when the user presses other keys i am doing some processing work, but when the user presses the Enter key i am submitting the value in the textbox to some server. I am able to do all processing and every thing is fine, but when i press enter key the event is not getting fired. so, i ma unable to submit my value to the server.

Here is my code:

$("#txt" + filterID).keypress(txtInput_keypress);

function txtInput_keypress(e) { 
    var code = (e.keyCode ? e.keyCode : e.which);
    var strValue = $(this).val()+ String.fromCharCode(e.which);
    var bool = $.trim(strValue).match(reg); 
    if (code == 13) {  
        //textbox value submission code
    }
    else if (parseFloat($.trim(strValue)) > max) {
        e.preventDefault();
    }
    else if (bool) {  
        return true;
    }
    else {
        e.preventDefault();
    }  
}

whats wrong with my code? Please somebody help me to fix this issue.
