I could not find where you are calling the getValue() function also you are not returning anything from your addAccounts() method. Below is the working version of your code. I tried to update the code to meet your requirement. I am calling getValue() method form onkeyup() event on the input text. The addAccounts() is now returning Account object matching the name. You can update further based on your need. Hope this helps.

public account a {get; set;}
@RemoteAction
    public static Account addAccounts(string acc){
       String ac = '%' + acc.Substring(0,acc.length()-1) +'%';

       system.debug(a);
