   发现只在默认只输入一个字符才会出现这个bug。应该原生的Edittext 
在输入值setValue会触犯onTextChanged事件，weex在setValue时候通过mIgnoreNextOnInputEvent变量对这种情况进行了过滤从处理。原因是AbstractEditComponent.java文件中当删除一个字符时候会触犯onTextChanged事件，
   ` 
   public void onTextChanged(CharSequence s, int start, int before, int count) {
                       if (mIgnoreNextOnInputEvent) {
                           mIgnoreNextOnInputEvent = false;
                          return;
                       }
                       if (mBeforeText.equals(s.toString())) {
                           return;
                       }
   `
   当删除一个字符时候 ，这时候mBeforeText.equals(s.toString()) 成立都是空值，所以返回不触发事件。
   可修改如：
   `    if (mIgnoreNextOnInputEvent) {
                  mIgnoreNextOnInputEvent = false;
                  mBeoreText = s.toString();
                  return;
                       }
   `
